Download or read book Higher Index Theory written by Rufus Willett and published by Cambridge University Press. This book was released on 2020-07-02 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: Index theory studies the solutions to differential equations on geometric spaces, their relation to the underlying geometry and topology, and applications to physics. If the space of solutions is infinite dimensional, it becomes necessary to generalise the classical Fredholm index using tools from the K-theory of operator algebras. This leads to higher index theory, a rapidly developing subject with connections to noncommutative geometry, large-scale geometry, manifold topology and geometry, and operator algebras. Aimed at geometers, topologists and operator algebraists, this book takes a friendly and concrete approach to this exciting theory, focusing on the main conjectures in the area and their applications outside of it. A well-balanced combination of detailed introductory material (with exercises), cutting-edge developments and references to the wider literature make this a valuable guide to this active area for graduate students and experts alike.

Download or read book Invariance Theory written by Peter B. Gilkey and published by CRC Press. This book was released on 1994-12-22 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book treats the Atiyah-Singer index theorem using the heat equation, which gives a local formula for the index of any elliptic complex. Heat equation methods are also used to discuss Lefschetz fixed point formulas, the Gauss-Bonnet theorem for a manifold with smooth boundary, and the geometrical theorem for a manifold with smooth boundary. The author uses invariance theory to identify the integrand of the index theorem for classical elliptic complexes with the invariants of the heat equation.
Download or read book The Economic Theory of Price Indices written by Franklin M. Fisher and published by Academic Press. This book was released on 2014-05-10 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Economic Theory of Price Indices: Two Essays on the Effects of Taste, Quality, and Technological Change is concerned with the effects of consumer taste, product quality, and technological change on price indices. Special attention is paid on technological change in the simple two-sector production model of Rybczynski and Uzawa. The effects of the general case of changing factor supplies and factor-augmenting change on the real national output deflator are also examined. Comprised of two essays, this book begins with an analysis of the pure theory of the true cost-of-living index, which may be considered as an idealization of indices like the consumer price index and others of that type. The essay explores how the true cost-of-living index is affected by changes in consumer taste, quality changes in purchased goods, and the introduction of new goods into the market place. The second essay deals with the pure theory of the national output deflator and provides a foundation for the measurement of real national output (or product). It shows that the usual inequalities relating Paasche and Laspeyres to the true index are reversed (from what they are in cost-of-living theory) for the case of production. It also assesses the implications of changing production possibilities caused by technological change or a change in factor supplies. This monograph will be a useful resource for mathematicians, economists, and others interested in economic theory and mathematical economics.
Download or read book An Index of a Graph with Applications to Knot Theory written by Kunio Murasugi and published by American Mathematical Soc.. This book was released on 1993 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are three chapters to the memoir. The first defines and develops the notion of the index of a graph. The next chapter presents the general application of the graph index to knot theory. The last section is devoted to particular examples, such as determining the braid index of alternating pretzel links. A second result shows that for an alternating knot with Alexander polynomial having leading coefficient less than 4 in absolute value, the braid index is determined by polynomial invariants.
Download or read book Relative Index Theory Determinants and Torsion for Open Manifolds written by Jrgen Eichhorn and published by World Scientific. This book was released on 2009 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: For closed manifolds, there is a highly elaborated theory of number-valued invariants, attached to the underlying manifold, structures and differential operators. On open manifolds, nearly all of this fails, with the exception of some special classes. The goal of this monograph is to establish for open manifolds, structures and differential operators an applicable theory of number-valued relative invariants. This is of great use in the theory of moduli spaces for nonlinear partial differential equations and mathematical physics. The book is self-contained: in particular, it contains an outline of the necessary tools from nonlinear Sobolev analysis.

Download or read book Index Numbers in Economic Theory and Practice written by R. G. D. Allen and published by Routledge. This book was released on 2017-07-12 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is no book currently available that gives a comprehensive treatment of the design, construction, and use of index numbers. However, there is a pressing need for one in view of the increasing and more sophisticated employment of index numbers in the whole range of applied economics and specifically in discussions of macroeconomic policy. In this book, R. G. D. Allen meets this need in simple and consistent terms and with comprehensive coverage. The text begins with an elementary survey of the index-number problem before turning to more detailed treatments of the theory and practice of index numbers. The binary case in which one time period is compared with another is first developed and illustrated with numerous examples. This is to prepare the ground for the central part of the text on runs of index numbers. Particular attention is paid both to fixed-weighted and to chain forms as used in a wide range of published index numbers taken mainly from British official sources. This work deals with some further problems in the construction of index numbers, problems which are both troublesome and largely unresolved. These include the use of sampling techniques in index-number design and the theoretical and practical treatment of quality changes. It is also devoted to a number of detailed and specific applications of index-number techniques to problems ranging from national-income accounting, through the measurement of inequality of incomes and international comparisons of real incomes, to the use of index numbers of stock-market prices. Aimed primarily at students of economics, whatever their age and range of interests, this work will also be of use to those who handle index numbers professionally.
Download or read book Property Price Index written by W. Erwin Diewert and published by Springer. This book was released on 2020-01-25 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book answers the question of how exactly property price indexes should be constructed. The formation and collapse of property bubbles has had a profound impact on the economic administration of many nations. The property price bubble that began around the mid-1980s in Japan has been called the 20th century's biggest bubble. In its aftermath, the country faced a period of long-term economic stagnation dubbed the "lost decade." Sweden and the United States have also faced collapses of property bubbles in the 20th and early 21st centuries, respectively. It has been pointed out that the "information gap" that existed between policy-making authorities and the property (including housing) and financial markets was a problem. In 2009, the IMF proposed the creation of a housing price index to the G20 in order to fill this information gap, and the proposal was adopted. Furthermore, in 2011, it was suggested that the next economic crisis would be caused by a bubble in commercial property prices, and it was decided to create a commercial property index as well. This book provides practical examples of how the theory of property price indexes can be applied to the issues of property as a non-homogenous good and a technological and environmental change.

Download or read book Index Theory and Price Statistics written by Peter von der Lippe and published by Peter Lang Gmbh, Internationaler Verlag Der Wissenschaften. This book was released on 2007 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook integrates mathematical index theory and its application in official price statistics. It tries to bridge theory and practice, due to the apparent divergence between mathematicians with ever more sophisticated and complex models and practitioners with problems that are more and more difficult to understand without broad knowledge and some experience. The text offers an introduction into axiomatic, microeconomic and stochastic reasoning as regards index numbers, with moderately difficult mathematics. It also summarizes many ongoing discussions concerning methodological merits and demerits of specific indices, such as consumer price-, producer price-, unit value- and chain indices, in official price statistics. The book is comprehensive and presents a readable overview of a great number of topics in modern price index theory and their application in inflation measurement, deflation of aggregates in National Accounts, sampling and quality adjustment in price collection and other important though controversial issues.
Download or read book Topology and Analysis written by D.D. Bleecker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Motivation. With intensified use of mathematical ideas, the methods and techniques of the various sciences and those for the solution of practical problems demand of the mathematician not only greater readi ness for extra-mathematical applications but also more comprehensive orientations within mathematics. In applications, it is frequently less important to draw the most far-reaching conclusions from a single mathe matical idea than to cover a subject or problem area tentatively by a proper "variety" of mathematical theories. To do this the mathematician must be familiar with the shared as weIl as specific features of differ ent mathematical approaches, and must have experience with their inter connections. The Atiyah-Singer Index Formula, "one of the deepest and hardest results in mathematics", "probably has wider ramifications in topology and analysis than any other single result" (F. Hirzebruch) and offers perhaps a particularly fitting example for such an introduction to "Mathematics": In spi te of i ts difficulty and immensely rich interrela tions, the realm of the Index Formula can be delimited, and thus its ideas and methods can be made accessible to students in their middle * semesters. In fact, the Atiyah-Singer Index Formula has become progressively "easier" and "more transparent" over the years. The discovery of deeper and more comprehensive applications (see Chapter 111. 4) brought with it, not only a vigorous exploration of its methods particularly in the many facetted and always new presentations of the material by M. F.

Download or read book A Course in Operator Theory written by John B. Conway and published by American Mathematical Soc.. This book was released on 2000 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operator theory is a significant part of many important areas of modern mathematics: functional analysis, differential equations, index theory, representation theory, mathematical physics, and more. This text covers the central themes of operator theory, presented with the excellent clarity and style that readers have come to associate with Conway's writing. Early chapters introduce and review material on $C^*$-algebras, normal operators, compact operators, and non-normal operators. Some of the major topics covered are the spectral theorem, the functional calculus, and the Fredholm index. In addition, some deep connections between operator theory and analytic functions are presented. Later chapters cover more advanced topics, such as representations of $C^*$-algebras, compact perturbations, and von Neumann algebras. Major results, such as the Sz.-Nagy Dilation Theorem, the Weyl-von Neumann-Berg Theorem, and the classification of von Neumann algebras, are covered, as is a treatment of Fredholm theory. The last chapter gives an introduction to reflexive subspaces, which along with hyperreflexive spaces, are one of the more successful episodes in the modern study of asymmetric algebras. Professor Conway's authoritative treatment makes this a compelling and rigorous course text, suitable for graduate students who have had a standard course in functional analysis.
