Joinings


Book Description

The first comprehensive study of the use of compound words in Old English poetry, homilies, and philosophy, Joinings explores the effect of compounds on style, pace, clarity, and genre in Anglo-Saxon vernacular literature. Jonathan Davis-Secord demonstrates how compounds affect the pacing of passages in Beowulf, creating slow-motion narrative at moments of significant violence; how their structural complexity gives rhetorical emphasis to phrases in the homilies of Wulfstan; and how they help to mix quotidian and elevated diction in Cynewulf's Juliana and the Old English translations of Boethius. His work demonstrates that compound words were the epitome of Anglo-Saxon vernacular verbal art, combining grammar, style, and culture in a manner unlike any other feature of Old English.




Ergodic Theory via Joinings


Book Description

This book introduces modern ergodic theory. It emphasizes a new approach that relies on the technique of joining two (or more) dynamical systems. This approach has proved to be fruitful in many recent works, and this is the first time that the entire theory is presented from a joining perspective. Another new feature of the book is the presentation of basic definitions of ergodic theory in terms of the Koopman unitary representation associated with a dynamical system and the invariant mean on matrix coefficients, which exists for any acting groups, amenable or not. Accordingly, the first part of the book treats the ergodic theory for an action of an arbitrary countable group. The second part, which deals with entropy theory, is confined (for the sake of simplicity) to the classical case of a single measure-preserving transformation on a Lebesgue probability space.




Ergodic Theory


Book Description

This volume in the Encyclopedia of Complexity and Systems Science, Second Edition, covers recent developments in classical areas of ergodic theory, including the asymptotic properties of measurable dynamical systems, spectral theory, entropy, ergodic theorems, joinings, isomorphism theory, recurrence, nonsingular systems. It enlightens connections of ergodic theory with symbolic dynamics, topological dynamics, smooth dynamics, combinatorics, number theory, pressure and equilibrium states, fractal geometry, chaos. In addition, the new edition includes dynamical systems of probabilistic origin, ergodic aspects of Sarnak's conjecture, translation flows on translation surfaces, complexity and classification of measurable systems, operator approach to asymptotic properties, interplay with operator algebras




Mathematics of Complexity and Dynamical Systems


Book Description

Mathematics of Complexity and Dynamical Systems is an authoritative reference to the basic tools and concepts of complexity, systems theory, and dynamical systems from the perspective of pure and applied mathematics. Complex systems are systems that comprise many interacting parts with the ability to generate a new quality of collective behavior through self-organization, e.g. the spontaneous formation of temporal, spatial or functional structures. These systems are often characterized by extreme sensitivity to initial conditions as well as emergent behavior that are not readily predictable or even completely deterministic. The more than 100 entries in this wide-ranging, single source work provide a comprehensive explication of the theory and applications of mathematical complexity, covering ergodic theory, fractals and multifractals, dynamical systems, perturbation theory, solitons, systems and control theory, and related topics. Mathematics of Complexity and Dynamical Systems is an essential reference for all those interested in mathematical complexity, from undergraduate and graduate students up through professional researchers.




Surveys in Modern Mathematics


Book Description

This collection of articles from the Independent University of Moscow is derived from the Globus seminars held there. They are given by world authorities, from Russia and elsewhere, in various areas of mathematics and are designed to introduce graduate students to some of the most dynamic areas of mathematical research. The seminars aim to be informal, wide-ranging and forward-looking, getting across the ideas and concepts rather than formal proofs, and this carries over to the articles here. Topics covered range from computational complexity, algebraic geometry, dynamics, through to number theory and quantum groups. The volume as a whole is a fascinating and exciting overview of contemporary mathematics.




On the Way to Heidegger’s Contributions to Philosophy


Book Description

One of the most significant philosophical works of the twentieth century, Contributions to Philosophy is also one of the most difficult. Parvis Emad, in this collection of interpretive and critical essays, unravels and clarifies this challenging work with a rare depth and originality. In addition to grappling with other commentaries on Heidegger, he highlights Heidegger's "being-historical thinking" as thinking that sheds new light on theological, technological, and scientific interpretations of reality. At the crux of Emad's interpretation is his elucidation of the issue of "the turning" in Heidegger's thought and his "enactment" of Heidegger's thinking. He finds that only when Heidegger's work is enacted is his thinking truly revealed.




Entropy in Dynamical Systems


Book Description

This comprehensive text on entropy covers three major types of dynamics: measure preserving transformations; continuous maps on compact spaces; and operators on function spaces. Part I contains proofs of the Shannon–McMillan–Breiman Theorem, the Ornstein–Weiss Return Time Theorem, the Krieger Generator Theorem and, among the newest developments, the ergodic law of series. In Part II, after an expanded exposition of classical topological entropy, the book addresses symbolic extension entropy. It offers deep insight into the theory of entropy structure and explains the role of zero-dimensional dynamics as a bridge between measurable and topological dynamics. Part III explains how both measure-theoretic and topological entropy can be extended to operators on relevant function spaces. Intuitive explanations, examples, exercises and open problems make this an ideal text for a graduate course on entropy theory. More experienced researchers can also find inspiration for further research.
