Is an arbitrary diffused Borel probability measure in a Polish space without isolated points Haar measure?
Abstract
It is introduced a certain approach for equipment of an arbitrary set of the cardinality of the continuum by structures of Polish groups and two-sided (left or right) invariant Haar measures. By using this approach we answer positively Maleki's certain question(2012) {\it what are the real -dimensional manifolds with at least two different Lie group structures that have the same Haar measure.} It is demonstrated that for each diffused Borel probability measure defined in a Polish space without isolated points there exist a metric and a group operation in such that and stands a compact Polish group with a two-sided (left or right) invariant Haar measure , where and denote Borel algebras of subsets of generated by metrics and , respectively. Similar result is obtained for construction of locally compact non-compact or non-locally compact Polish groups equipped with two-sided (left or right) invariant quasi-finite Borel measures.
