Download or read book Real Analysis with Economic Applications written by Efe A. Ok and published by Princeton University Press. This book was released on 2011-09-05 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many mathematics textbooks on real analysis, but they focus on topics not readily helpful for studying economic theory or they are inaccessible to most graduate students of economics. Real Analysis with Economic Applications aims to fill this gap by providing an ideal textbook and reference on real analysis tailored specifically to the concerns of such students. The emphasis throughout is on topics directly relevant to economic theory. In addition to addressing the usual topics of real analysis, this book discusses the elements of order theory, convex analysis, optimization, correspondences, linear and nonlinear functional analysis, fixed-point theory, dynamic programming, and calculus of variations. Efe Ok complements the mathematical development with applications that provide concise introductions to various topics from economic theory, including individual decision theory and games, welfare economics, information theory, general equilibrium and finance, and intertemporal economics. Moreover, apart from direct applications to economic theory, his book includes numerous fixed point theorems and applications to functional equations and optimization theory. The book is rigorous, but accessible to those who are relatively new to the ways of real analysis. The formal exposition is accompanied by discussions that describe the basic ideas in relatively heuristic terms, and by more than 1,000 exercises of varying difficulty. This book will be an indispensable resource in courses on mathematics for economists and as a reference for graduate students working on economic theory.

Download or read book Be sparse Be dense Be robust written by Sorge, Manuel and published by Universitätsverlag der TU Berlin. This book was released on 2017-05-31 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis we study the computational complexity of five NP-hard graph problems. It is widely accepted that, in general, NP-hard problems cannot be solved efficiently, that is, in polynomial time, due to many unsuccessful attempts to prove the contrary. Hence, we aim to identify properties of the inputs other than their length, that make the problem tractable or intractable. We measure these properties via parameters, mappings that assign to each input a nonnegative integer. For a given parameter k, we then attempt to design fixed-parameter algorithms, algorithms that on input q have running time upper bounded by f(k(q)) * |q|^c , where f is a preferably slowly growing function, |q| is the length of q, and c is a constant, preferably small. In each of the graph problems treated in this thesis, our input represents the setting in which we shall find a solution graph. In addition, the solution graphs shall have a certain property specific to our five graph problems. This property comes in three flavors. First, we look for a graph that shall be sparse! That is, it shall contain few edges. Second, we look for a graph that shall be dense! That is, it shall contain many edges. Third, we look for a graph that shall be robust! That is, it shall remain a good solution, even when it suffers several small modifications. Be sparse! In this part of the thesis, we analyze two similar problems. The input for both of them is a hypergraph H , which consists of a vertex set V and a family E of subsets of V , called hyperedges. The task is to find a support for H , a graph G such that for each hyperedge W in E we have that G[W ] is connected. Motivated by applications in network design, we study SUBSET INTERCONNECTION DESIGN, where we additionally get an integer f , and the support shall contain at most |V| - f + 1 edges. We show that SUBSET INTERCONNECTION DESIGN admits a fixed-parameter algorithm with respect to the number of hyperedges in the input hypergraph, and a fixed-parameter algorithm with respect to f + d , where d is the size of a largest hyperedge. Motivated by an application in hypergraph visualization, we study r-OUTERPLANAR SUPPORT where the support for H shall be r -outerplanar, that is, admit a edge-crossing free embedding in the plane with at most r layers. We show that r-OUTER-PLANAR SUPPORT admits a fixed-parameter algorithm with respect to m + r , where m is the number of hyperedges in the input hypergraph H. Be dense! In this part of the thesis, we study two problems motivated by community detection in social networks. Herein, the input is a graph G and an integer k. We look for a subgraph G' of G containing (exactly) k vertices which adheres to one of two mathematically precise definitions of being dense. In mu-CLIQUE, 0 < mu <= 1, the sought k-vertex subgraph G' should contain at least mu time k choose 2 edges. We study the complexity of mu-CLIQUE with respect to three parameters of the input graph G: the maximum vertex degree delta, h-index h, and degeneracy d. We have delta >= h >= d in every graph and h as well as d assume small values in graphs derived from social networks. For delta and for h, respectively, we obtain fixed-parameter algorithms for mu-CLIQUE and we show that for d + k a fixed-parameter algorithm is unlikely to exist. We prove the positive algorithmic results via developing a general framework for optimizing objective functions over k-vertex subgraphs. In HIGHLY CONNECTED SUBGRAPH we look for a k-vertex subgraph G' in which each vertex shall have degree at least floor(k/2)+1. We analyze a part of the so-called parameter ecology for HIGHLY CONNECTED SUBGRAPH, that is, we navigate the space of possible parameters in a quest to find a reasonable trade-off between small parameter values in practice and efficient running time guarantees. The highlights are that no 2^o(n) * n^c -time algorithms are possible for n-vertex input graphs unless the Exponential Time Hypothesis fails; that there is a O(4^g * n^2)-time algorithm for the number g of edges outgoing from the solution G; and we derive a 2^(O(sqrt(a)log(a)) + a^2nm-time algorithm for the number a of edges not in the solution. Be robust! In this part of the thesis, we study the VECTOR CONNECTIVITY problem, where we are given a graph G, a vertex labeling ell from V(G) to {1, . . . , d }, and an integer k. We are to find a vertex subset S of V(G) of size at most k such that each vertex v in V (G)\S has ell(v) vertex-disjoint paths from v to S in G. Such a set S is useful when placing servers in a network to satisfy robustness-of-service demands. We prove that VECTOR CONNECTIVITY admits a randomized fixed-parameter algorithm with respect to k, that it does not allow a polynomial kernelization with respect to k + d but that, if d is treated as a constant, then it allows a vertex-linear kernelization with respect to k. In dieser Dissertation untersuchen wir die Berechnungskomplexität von fünf NP-schweren Graphproblemen. Es wird weithin angenommen, dass NP-schwere Probleme im Allgemeinen nicht effizient gelöst werden können, das heißt, dass sie keine Polynomialzeitalgorithmen erlauben. Diese Annahme basiert auf vielen bisher nicht erfolgreichen Versuchen das Gegenteil zu beweisen. Aus diesem Grund versuchen wir Eigenschaften der Eingabe herauszuarbeiten, die das betrachtete Problem handhabbar oder unhandhabbar machen. Solche Eigenschaften messen wir mittels Parametern, das heißt, Abbildungen, die jeder möglichen Eingabe eine natürliche Zahl zuordnen. Für einen gegebenen Parameter k versuchen wir dann Fixed-Parameter Algorithmen zu entwerfen, also Algorithmen, die auf Eingabe q eine obere Laufzeitschranke von f(k(q)) * |q|^c erlauben, wobei f eine, vorzugsweise schwach wachsende, Funktion ist, |q| die Länge der Eingabe, und c eine Konstante, vorzugsweise klein. In den Graphproblemen, die wir in dieser Dissertation studieren, repräsentiert unsere Eingabe eine Situation in der wir einen Lösungsgraph finden sollen. Zusätzlich sollen die Lösungsgraphen bestimmte problemspezifische Eigenschaften haben. Wir betrachten drei Varianten dieser Eigenschaften: Zunächst suchen wir einen Graphen, der sparse sein soll. Das heißt, dass er wenige Kanten enthalten soll. Dann suchen wir einen Graphen, der dense sein soll. Das heißt, dass er viele Kanten enthalten soll. Zuletzt suchen wir einen Graphen, der robust sein soll. Das heißt, dass er eine gute Lösung bleiben soll, selbst wenn er einige kleine Modifikationen durchmacht. Be sparse! In diesem Teil der Arbeit analysieren wir zwei ähnliche Probleme. In beiden ist die Eingabe ein Hypergraph H, bestehend aus einer Knotenmenge V und einer Familie E von Teilmengen von V, genannt Hyperkanten. Die Aufgabe ist einen Support für H zu finden, einen Graphen G, sodass für jede Hyperkante W in E der induzierte Teilgraph G[W] verbunden ist. Motiviert durch Anwendungen im Netzwerkdesign betrachten wir SUBSET INTERCONNECTION DESIGN, worin wir eine natürliche Zahl f als zusätzliche Eingabe bekommen, und der Support höchstens |V| - f + 1 Kanten enthalten soll. Wir zeigen, dass SUBSET INTERCONNECTION DESIGN einen Fixed-Parameter Algorithmus in Hinsicht auf die Zahl der Hyperkanten im Eingabegraph erlaubt, und einen Fixed-Parameter Algorithmus in Hinsicht auf f + d, wobei d die Größe einer größten Hyperkante ist. Motiviert durch eine Anwendung in der Hypergraphvisualisierung studieren wir r-OUTERPLANAR SUPPORT, worin der Support für H r-outerplanar sein soll, das heißt, er soll eine kantenkreuzungsfreie Einbettung in die Ebene erlauben mit höchstens r Schichten. Wir zeigen, dass r-OUTERPLANAR SUPPORT einen Fixed-Parameter Algorithmus in Hinsicht auf m + r zulässt, wobei m die Anzahl der Hyperkanten im Eingabehypergraphen H ist. Be dense! In diesem Teil der Arbeit studieren wir zwei Probleme, die durch Community Detection in sozialen Netzwerken motiviert sind. Dabei ist die Eingabe ein Graph G und eine natürliche Zahl k. Wir suchen einen Teilgraphen G' von G, der (genau) k Knoten enthält und dabei eine von zwei mathematisch präzisen Definitionen davon, dense zu sein, aufweist. In mu-CLIQUE, 0 < mu <= 1, soll der gesuchte Teilgraph G' mindestens mu mal k über 2 Kanten enthalten. Wir studieren die Berechnungskomplexität von mu-CLIQUE in Hinsicht auf drei Parameter des Eingabegraphen G: dem maximalen Knotengrad delta, dem h-Index h, und der Degeneracy d. Es gilt delta >= h >= d für jeden Graphen und h als auch d nehmen kleine Werte in Graphen an, die aus sozialen Netzwerken abgeleitet sind. Für delta und h erhalten wir Fixed-Parameter Algorithmen für mu-CLIQUE und wir zeigen, dass für d + k wahrscheinlich kein Fixed-Parameter Algorithmus existiert. Unsere positiven algorithmischen Resultate erhalten wir durch Entwickeln eines allgemeinen Frameworks zum Optimieren von Zielfunktionen über k-Knoten-Teilgraphen. In HIGHLY CONNECTED SUBGRAPH soll in dem gesuchten k-Knoten-Teilgraphen G' jeder Knoten Knotengrad mindestens floor(k/2) + 1 haben. Wir analysieren einen Teil der sogenannten Parameter Ecology für HIGHLY CONNECTED SUBGRAPH. Das heißt, wir navigieren im Raum der möglichen Parameter auf der Suche nach einem vernünftigen Trade-off zwischen kleinen Parameterwerten in der Praxis und effizienten oberen Laufzeitschranken. Die Highlights hier sind, dass es keine Algorithmen mit 2^o(n) * poly(n)-Laufzeit für HIGHLY CONNECTED SUBGRAPH gibt, es sei denn die Exponential Time Hypothesis stimmt nicht; die Entwicklung eines Algorithmus mit O(4^y * n^2 )-Laufzeit, wobei y die Anzahl der Kanten ist, die aus dem Lösungsgraphen G' herausgehen; und die Entwicklung eines Algorithmus mit 2^O(sqrt(a) log(a)) + O(a^2nm)-Laufzeit, wobei a die Anzahl der Kanten ist, die nicht in G' enthalten sind.

Book excerpt: The only person seventy-seven-year-old Robert Landon recognizes is his daughter, Heather. Robert doesnt know his grandchildren, Carrie and Brian. But most importantly, Robert, suffering from the early stages of Alzheimers, doesnt know his wife, Jessica. Heather is determined to rectify this situation. She knows her parents forty-two-year relationship is a love story for the ages. Heather and Jessica concoct a plan to help jar Roberts memory, to remind him that his one true love is waiting for him. The doctor, however, warns that the plan could backfire, and Robert could become upset hearing the details of his past. From his birth in 1900 to attending college at New York University to becoming a US Senator, Heather recaps the details of Roberts life for him. She reminds him of his desire to be successful in the era prior to the Great Depression and how these events found him caught in a whirlwind of trouble: trouble with the law, trouble with trying to find a means of supporting himself, as well as trouble with an entangled weave of numerous women who were in awe of him. But will he ever be able to remember the woman from his past who calls him her husband?

Download or read book Degree constrained editing of small degree graphs written by Nichterlein, Andre and published by Universitätsverlag der TU Berlin. This book was released on 2015-07-03 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with degree-constrained graph modification problems. In particular, we investigate the computational complexity of DAG Realization and Degree Anonymity. The DAG Realization problem is, given a multiset of positive integer pairs, to decide whether there is a realizing directed acyclic graph (DAG), that is, pairs are one-to-one assigned to vertices such that the indegree and the outdegree of every vertex coincides with the two integers of the assigned pair. The Degree Anonymity problem is, given an undirected graph G and two positive integers k and s, to decide whether at most s graph modification operations can be performed in G in order to obtain a k-anonymous graph, that is, a graph where for each vertex there are k − 1 other vertices with the same degree. We classify both problems as NP-complete, that is, there are presumably no polynomial-time algorithms that can solve every instance of these problems. Confronted with this worst-case intractability, we perform a parameterized complexity study in order to detect efficiently solvable special cases that are still practically relevant. The goal herein is to develop fixed-parameter algorithms where the seemingly unavoidable exponential dependency in the running time is confined to a parameter of the input. If the parameter is small, then the corresponding fixed-parameter algorithm is fast. The parameter thus measures some structure in the input whose exploitation makes the particular input tractable. Considering Degree Anonymity, two natural parameters provided with the input are anonymity level k and solution size s. However, we will show that Degree Anonymity is W[1]-hard with respect to the parameter s even if k = 2. This means that the existence of fixed-parameter algorithms for s and k is very unlikely. Thus, other parameters have to be considered. We will show that the parameter maximum vertex degree is very promising for both DAG Realization and Degree Anonymity. Herein, for Degree Anonymity, we consider the maximum degree of the input graph. Considering DAG Realization, we take the maximum degree in a realizing DAG. Due to the problem definition, we can easily determine the maximum degree by taking the maximum over all integers in the given multiset. We provide fixed-parameter algorithms with respect to the maximum degree for DAG Realization and for Anonym E-Ins. The later is the variant of Degree Anonymity when only edge insertions are allowed as modification operations. If we allow edge deletions or vertex deletions as graph modification operations, then we can show that the corresponding variants of Degree Anonymity—called Anonym V-Del and Anonym E-Del—are NP-complete even if the maximum vertex degree is seven. Moreover, we provide strong intractability results for Anonym E-Del and Anonym V-Del proving that they remain NP-complete in several restricted graph classes. Studying the approximability of natural optimization problems associated with Anonym E-Del or Anonym V-Del, we obtain negative results showing that none of the considered problems can be approximated in polynomial time better than within a factor of n^(1/2) where n denotes the number of vertices in the input. Furthermore, for the optimization variants where the solution size s is given and the task is to maximize the anonymity level k, this inapproximability even holds if we allow a running time that is exponential in s. Observe that DAG Realization also can be seen as degree-constrained graph modification problem where only arc insertions are allowed: Starting with an arcless graph, the task is to insert arcs to obtain a realizing DAG for the given multiset. The above classification with respect to the parameter maximum degree shows that in graphs with small maximum degree the modification operation edge respectively arc insertion is easier than vertex or edge deletion. There is a plausible explanation for this behavior: When the maximum degree is small, then there is a high freedom in inserting edges or arcs as for a given vertex almost all other vertices can be chosen as new neighbor. Observe that for DAG Realization the additional requirement that the directed graph shall be acyclic restricts this freedom. In Anonym E-Ins, we do not have restrictions on this freedom. In fact, exploiting this freedom in our implementation for Anonym E-Ins, we show that our theoretical ideas can be turned into successful heuristics and lower bounds. Experiments on several large-scale real-world datasets show that our implementation significantly improves on a recent heuristic and provides (provably) optimal solutions on about 21 % (56 of 260) of the real-world data.

Book excerpt: Lucille Ball, Hollywood’s first true media mogul, stars in this “bold” (The Boston Globe), “boisterous novel” (The New Yorker) with a thrilling love story at its heart—from the award-winning, bestselling author of Chang & Eng and Half a Life A WASHINGTON POST BEST BOOK OF THE YEAR • “A gorgeous, Technicolor take on America in the middle of the twentieth century.”—Colson Whitehead, Pulitzer Prize–winning author of The Nickel Boys This indelible romance begins with a daring conceit—that the author’s grandfather may have had an affair with Lucille Ball. Strauss offers a fresh view of a celebrity America loved more than any other. Lucille Ball—the most powerful woman in the history of Hollywood—was part of America’s first high-profile interracial marriage. She owned more movie sets than did any movie studio. She more or less single-handedly created the modern TV business. And yet Lucille’s off-camera life was in disarray. While acting out a happy marriage for millions, she suffered in private. Her partner couldn’t stay faithful. She struggled to balance her fame with the demands of being a mother, a creative genius, an entrepreneur, and, most of all, a symbol. The Queen of Tuesday—Strauss’s follow-up to Half a Life, winner of the National Book Critics Circle Award—mixes fact and fiction, memoir and novel, to imagine the provocative story of a woman we thought we knew.
