Global Aspects Of Ergodic Group Actions

By Alexander S. Kechris, A. S. Kechris, Alexander Sotirios Kechris

The subject of this book is the study of ergodic, measure preserving actions of countable discrete groups on standard probability spaces. It explores a direction that emphasizes a global point of v...

Classical Descriptive Set Theory

By Alexander S. Kechris, Werner Kammerloher, Hans Werner Schneider

Descriptive set theory has been one of the main areas of research in set theory for almost a century. This text attempts to present a largely balanced approach, which combines many elements of the...

Classical descriptive set theory

By A. S. Kechris

Descriptive set theory is the area of mathematics concerned with the study of the structure of definable sets in Polish spaces. Beyond being a central part of contemporary set theory, the concepts...

Topics in orbit equivalence

By A. S. Kechris

This volume provides a self-contained introduction to some topics in orbit equivalence theory, a branch of ergodic theory. The first two chapters focus on hyperfiniteness and amenability. Included...
