Explanation of the Book:

The discovery of a virtual turning point truly is a breakthrough in WKB analysis of higher order differential equations. This monograph expounds the core part of its theory together with its application to the analysis of higher order Painlevé equations of the Noumi–Yamada type and to the analysis of non-adiabatic transition probability problems in three levels. As M.V. Fedoryuk once lamented, global asymptotic analysis of higher order differential equations had been thought to be impossible to construct. In 1982, however, H.L. Berk, W.M. Nevins, and K.V. Roberts published a remarkable paper in the Journal of Mathematical Physics indicating that the traditional Stokes geometry cannot globally describe the Stokes phenomena of solutions of higher order equations; a new Stokes curve is necessary.

Explanation of the Book:

At times of crisis and revolution such as ours, diagnoses of crucial junctures and ruptures – ‘turning points’ – in the continuous flow of history are more prevalent than ever. Analysing literary, cinematic and other narratives, the volume seeks to understand the meanings conveyed by different concepts of turning points, the alternative concepts to which they are opposed when used to explain historical change, and those contexts in which they are unmasked as false and over-simplifying constructions. Literature and film in particular stress the importance of turning points as a sensemaking device (as part of a character’s or a community’s cultural memory), while at the same time unfolding the constructive and hence relative character of turning points. Offering complex reflections on the notion of turning points, literary and filmic narratives are thus of particular interest to the present volume.

Improved WKB Phase Shift Via Virtual Turning Points for Waveguides with Index Discontinuities

Explanation of the Book:

The WKB method has been widely used to obtain approximate solutions of the guided mode propagation constants for optical waveguides with slowly varying graded-index profiles. One of the key features of the standard method, which is properly applied only to problems with isolated turning points, is the assumption of a constant phase shift (Pi/4) at a turning Point. However, it has long been known that when turning points are not isolated, but are instead near some other transition points, the phase shift is no longer constant. Here, we consider the presence of an index discontinuity near or at a turning point in an optical waveguide and present analytical expressions of the improved phase shift. The principle of this phase shift correction is based upon two main points. The first consists of using Airy functions as the field solutions at the discontinuity.

Explanation of the Book:

Artificial Intelligence is here, today. How can society make the best use of it? Until recently, “artificial intelligence” sounded like something out of science fiction. But the technology of artificial intelligence, AI, is becoming increasingly common, from self-driving cars to e-commerce algorithms that seem to know what you want to buy before you do. Throughout the economy and many aspects of daily life, artificial intelligence has become the transformative technology of our time. Despite its current and potential benefits, AI is little understood by the larger public and widely feared. The rapid growth of artificial intelligence has given rise to concerns that hidden technology will create a dystopian world of increased income inequality, a total lack of privacy, and perhaps a broad threat to humanity itself. In their compelling and readable book, two experts at Brookings discuss both the opportunities and risks posed by artificial intelligence—and how near-term policy decisions could determine whether the technology leads to utopia or dystopia. Drawing on in-depth studies of major uses of AI, the authors detail how the technology actually works. They outline a policy and governance blueprint for gaining the benefits of artificial intelligence while minimizing its potential downsides. The book offers major recommendations for actions that governments, businesses, and individuals can take to promote trustworthy and responsible artificial intelligence. Their recommendations include: creation of ethical principles, strengthening government oversight, defining corporate culpability, establishment of advisory boards at federal agencies, using third-party audits to reduce biases inherent in algorithms, tightening personal privacy requirements, using insurance to mitigate exposure to AI risks, broadening decision-making about AI uses and procedures, penalizing malicious uses of new technologies, and taking pro-active steps to address how artificial intelligence affects the workforce. Turning Point is essential reading for anyone concerned about how artificial intelligence works and what can be done to ensure its benefits outweigh its harm.

Explanation of the Book:

This book considers how people talk about their environment, find their way in new surroundings, and plan routes. Part I explores the empirical insights gained from research in the cognitive underpinnings of spatial representation in language. Part II proposes solutions for capturing such insights formally, and in Part III authors discuss how theory is put into practice through spatial assistance systems. These three perspectives stem from research disciplines which deal with the spatial domain in different ways, and which often remain separate. In this book they are combined so as to highlight both the state of the art in the field and the benefit of building bridges between methodologies and disciplines. Finding our way and planning routes is relevant to us all; this book ultimately helps improve our everyday lives.

Analyzable Functions and Applications

ISBN: 9780821834190
Available:

Editor: American Mathematical Soc.
Language: en

Explanation of the Book:

The theory of analyzable functions is a technique used to study a wide class of asymptotic expansion methods and their applications in analysis, difference and differential equations, partial differential equations and other areas of mathematics. Key ideas in the theory of analyzable functions were laid out by Euler, Cauchy, Stokes, Hardy, E. Borel, and others. Then in the early 1980s, this theory took a great leap forward with the work of J. Ecalle.Similar techniques and concepts in analysis, logic, applied mathematics and surreal number theory emerged at essentially the same time and developed rapidly through the 1990s. The links among various approaches soon became apparent and this body of ideas is now recognized as a field of its own with numerous applications. This volume stemmed from the International Workshop on Analyzable Functions and Applications held in Edinburgh (Scotland). The contributed articles, written by many leading experts, are suitable for graduate students and researchers interested in asymptotic methods.

Explanation of the Book:

This book is a collection of original papers on microlocal analysis, Fourier analysis in the complex domain, generalized functions and related topics. Most of the papers originate from the talks given at the conference “Prospects of Generalized Functions” (in November, 2001 at RIMS, Kyoto). Reflecting the fact that the papers, except M Morimoto's one, are dedicated to Mitsuo Morimoto, the subjects considered in this book are interdisciplinary, just as Morimoto's works are. The historical backgrounds of the subjects are also discussed in depth in some contributions. Thus, this book should be valuable not only to the specialists in the fields, but also to those who are interested in the history of modern mathematics such as distributions and hyperfunctions. Contents:Vanishing of Stokes Curves (T Aoki et al.)Parabolic Equations with Singularity on the Boundary (C P Arceo et al.)Residues: Analysis or Algebra?

Explanation of the Book:

orbit and far beyond it. Indeed, the immense, painstaking, indefatigable and ever-improving effort of Husserl to find ever-deeper and more reliable foundations for the philosophical enterprise (as well as his constant critical re-thinking and perfecting of the approach and so called "method" in order to perform this task and thus cover in this source-excavation an ever more far-reaching groundwork) stands out and maintains itself as an inepuisable reservoir for philosophical reflec tion in which all the above-mentioned work has either its core or its source. In fact, in his undertaking to re-think the entire philosophical enterprise as such and to recreate philosophy upon what he sought to be at least a satisfactorily legitimated basis, Husserl, through his already systematised and "authorized" work, and his courses, and later on in his spontaneous reflection (which did not find its way into a definitive corpus but was nevertheless sufficiently coherent with his previously established body of thought to be considered a continuation of it), uncovers perspectives upon the universe of man and projects their new philosophical thematisation that brings together all the attempts by philosophers (e. g. , Merleau-Ponty, who drew upon this material and found there his own inspiration) who succeeded him with foundational intentions; it also gives a core of philosophical ideas and insights for the youngergenerationofphilosophers today.

Explanation of the Book:

This book proposes a method for calculating China’s debt based on a quantitative econometric analysis. This is conducted by measuring the relationship between China’s debt size and economic growth. The conclusion that is reached is as follows: China’s current debt has already exceeded the inflection point, and that means that it is now having an adverse effect on its economic performance. The book also focuses on China's debt problems as a whole, highlighting debt issues faced by different entities and industries, as well as the ratio and structure of the virtual and real economies. The contents are presented in three major principles: theory, oriented,data, and oriented policy.
