On uniform permutations with finite dispersion parameters
Николай Михайлович Сучков, Yu. S. Tarasov · Proceedings of the Steklov Institute of Mathematics · 2014
We study the group G of uniform permutations of the set of integers with finite dispersion parameters. We prove that every finite subset of G lies in a subgroup of the form Q = AB , where A and B are locally finitely approximable subgroups of G .
