Download or read book On the Ambiguity of Erasing Morphisms written by Johannes C. Schneider and published by Logos Verlag Berlin GmbH. This book was released on 2012 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses a very basic and fundamental phenomenon in combinatorics on words, namely the ambiguity of morphisms: A morphism h is called ambiguous for a word w provided that there is another morphism g which satisfies g(w)=h(w). If such another morphism does not exist, h is called unambiguous for w. Furthermore, there are different types of restricted ambiguity which make additional demands on the other morphism g. The examination of the ambiguity of morphisms is not only of intrinsic interest, but, due to the simplicity of the concept, also shows various connections to other topics in theoretical computer science and discrete mathematics, pattern languages and various other concepts as fixed points of morphisms, avoidable patterns and word equations. This book is the first comprehensive study of the ambiguity of erasing morphisms, i., e., morphisms that are allowed to map symbols in the word to the empty word

Download or read book Handbook of Weighted Automata written by Manfred Droste and published by Springer Science & Business Media. This book was released on 2009-09-18 with total page 614 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this Handbook is to highlight both theory and applications of weighted automata. Weighted finite automata are classical nondeterministic finite automata in which the transitions carry weights. These weights may model, e. g. , the cost involved when executing a transition, the amount of resources or time needed for this,or the probability or reliability of its successful execution. The behavior of weighted finite automata can then be considered as the function (suitably defined) associating with each word the weight of its execution. Clearly, weights can also be added to classical automata with infinite state sets like pushdown automata; this extension constitutes the general concept of weighted automata. To illustrate the diversity of weighted automata, let us consider the following scenarios. Assume that a quantitative system is modeled by a classical automaton in which the transitions carry as weights the amount of resources needed for their execution. Then the amount of resources needed for a path in this weighted automaton is obtained simply as the sum of the weights of its transitions. Given a word, we might be interested in the minimal amount of resources needed for its execution, i. e. , for the successful paths realizing the given word. In this example, we could also replace the “resources” by “profit” and then be interested in the maximal profit realized, correspondingly, by a given word.

Download or read book Problems on Mapping Class Groups and Related Topics written by Benson Farb and published by American Mathematical Soc.. This book was released on 2006-09-12 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The appearance of mapping class groups in mathematics is ubiquitous. The book presents 23 papers containing problems about mapping class groups, the moduli space of Riemann surfaces, Teichmuller geometry, and related areas. Each paper focusses completely on open problems and directions. The problems range in scope from specific computations, to broad programs. The goal is to have a rich source of problems which have been formulated explicitly and accessibly. The book is divided into four parts. Part I contains problems on the combinatorial and (co)homological group-theoretic aspects of mapping class groups, and the way in which these relate to problems in geometry and topology. Part II concentrates on connections with classification problems in 3-manifold theory, the theory of symplectic 4-manifolds, and algebraic geometry. A wide variety of problems, from understanding billiard trajectories to the classification of Kleinian groups, can be reduced to differential and synthetic geometry problems about moduli space. Such problems and connections are discussed in Part III. Mapping class groups are related, both concretely and philosophically, to a number of other groups, such as braid groups, lattices in semisimple Lie groups, and automorphism groups of free groups. Part IV concentrates on problems surrounding these relationships. This book should be of interest to anyone studying geometry, topology, algebraic geometry or infinite groups. It is meant to provide inspiration for everyone from graduate students to senior researchers.
Download or read book How Forests Think written by Eduardo Kohn and published by Univ of California Press. This book was released on 2013-08-10 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: Can forests think? Do dogs dream? In this astonishing book, Eduardo Kohn challenges the very foundations of anthropology, calling into question our central assumptions about what it means to be humanÑand thus distinct from all other life forms. Based on four years of fieldwork among the Runa of EcuadorÕs Upper Amazon, Eduardo Kohn draws on his rich ethnography to explore how Amazonians interact with the many creatures that inhabit one of the worldÕs most complex ecosystems. Whether or not we recognize it, our anthropological tools hinge on those capacities that make us distinctly human. However, when we turn our ethnographic attention to how we relate to other kinds of beings, these tools (which have the effect of divorcing us from the rest of the world) break down. How Forests Think seizes on this breakdown as an opportunity. Avoiding reductionistic solutions, and without losing sight of how our lives and those of others are caught up in the moral webs we humans spin, this book skillfully fashions new kinds of conceptual tools from the strange and unexpected properties of the living world itself. In this groundbreaking work, Kohn takes anthropology in a new and exciting directionÐone that offers a more capacious way to think about the world we share with other kinds of beings.
