Nilpotent Structures in Ergodic Theory
Share this pageBernard Host; Bryna Kra
Nilsystems play a key role in the structure
theory of measure preserving systems, arising as the natural objects
that describe the behavior of multiple ergodic averages. This book is
a comprehensive treatment of their role in ergodic theory, covering
development of the abstract theory leading to the structural
statements, applications of these results, and connections to other
fields.
Starting with a summary of the relevant dynamical background, the
book methodically develops the theory of cubic structures that give
rise to nilpotent groups and reviews results on nilsystems and their
properties that are scattered throughout the literature. These basic
ingredients lay the groundwork for the ergodic structure theorems, and
the book includes numerous formulations of these deep results, along
with detailed proofs. The structure theorems have many applications,
both in ergodic theory and in related fields; the book develops the
connections to topological dynamics, combinatorics, and number theory,
including an overview of the role of nilsystems in each of these
areas. The final section is devoted to applications of the structure
theory, covering numerous convergence and recurrence results.
The book is aimed at graduate students and researchers in ergodic
theory, along with those who work in the related areas of arithmetic
combinatorics, harmonic analysis, and number theory.
