Query: On concentration of convolutions of double cosets at
  infinite-dimensional limit   For infinite-dimensional groups $G\supset K$ the double cosets $K\setminus
G/K$ quite often admit a structure of a semigroup; these semigroups act in
$K$-fixed vectors of unitary representations of $G$. We show that such
semigroups can be obtained as limits of double cosets hypergroups (or
Iwahori--Hecke type algebras) on finite-dimensional (or finite) groups.
