Abstract

We classify all irreducible admissible representations of three Olshanski pairs connected to the infinite symmetric group S(∞). In particular, our methods yield two simple proofs of the classical Thoma description of the characters of S(∞). Also, we discuss a certain operation, called a mixture of representations, that provides a uniform construction of all irreducible admissible representations.
