Beyond Haar and Cameron-Martin: the Steinhaus support

Functional Analysis 2019-03-18 v3 General Topology

Abstract

Motivated by a Steinhaus-like interior-point property involving the Cameron-Martin space of Gaussian measure theory, we study a group-theoretic analogue, the Steinhaus triple (H,G,μ)(H,G,\mu), and construct a Steinhaus support, a Cameron-Martin-like subset, H(μ)H(\mu) in any Polish group GG corresponding to `sufficiently subcontinuous' measures μ\mu, in particular for `Solecki-type' reference measures.
