Stable representations of the infinite symmetric group

Izvestiya: Mathematics, 2015
We study the notion of a stable unitary representation of a group (or a -representation of a -algebra) with respect to some group of automorphisms of the group (or algebra). In the case of the group of finitary permutations of a countable set we give a complete description, up to quasi-equivalence, of the representations which are stable with respect ...

Representations of the Infinite Symmetric Group

2016
Representation theory of big groups is an important and quickly developing part of modern mathematics, giving rise to a variety of important applications in probability and mathematical physics. This book provides the first concise and self-contained introduction to the theory on the simplest yet very nontrivial example of the infinite symmetric group,

Characters of projective representations of the infinite generalized symmetric group

Sbornik: Mathematics, 2008
By the infinite generalized symmetric group we mean the group , where is the group of all sequences in containing only finitely many non-zero elements and is the group of all finitely supported permutations of the positive integers. A complete description of the projective factor representations of of finite type is obtained.Bibliography: 18 titles.
