Semigroup approach to admissible representations of the infinite symmetric group

Irina Devyatkova

Let $S (\infty)$ denote the group of finitary permutations of the set $N := {1, 2, 3, \dots}$ . It is a countable group admitting a lot of different topologies compatible with t…

Limits of group algebras for growing symmetric groups and wreath products

Irina Devyatkova, Grigori Olshanski

Let $S (\infty)$ denote the infinite symmetric group formed by the finitary permutations of the set of natural numbers; this is a countable group. We introduce its virtual group alg…
