The dual space of precompact groups

Representation Theory 2021-08-30 v1

Abstract

For any topological group GG the dual object G^\hat G is defined as the set of equivalence classes of irreducible unitary representations of GG equipped with the Fell topology. If GG is compact, G^\hat G is discrete. In an earlier paper we proved that G^\hat G is discrete for every metrizable precompact group, i.e. a dense subgroup of a compact metrizable group. We generalize this result to the case when GG is an almost metrizable precompact group.
