Geometric stability theory for mu-structure

Submission date: 16 June 2018

Abstract:

We introduce a notion of mu-structure which are certain locally compact group actions and prove some counterparts of results on Polish structures. Mainly, using the Haar measure of locally compact groups, we introduce an independence notion, called mu-independence, satisfying invariance, symmetry, transitivity, and extension under the assumption of smallness.
