On Invariant measures concentrated on countable structures part 2
Abstract: We continue the discussion of ``Invariant measures concentrated on countable structures'', by Ackerman-Freer-Patel . We show how to obtain a Borel L-structure witnessing the pithy $\Pi_2$ expansion of the Scott sentence of a countable L-structure with trivial group theoretic definable closure.
