Invariant measures in simple and in small theories
We give examples of (i) a simple theory with a formula (with parameters) which does not fork over ∅ but has 𝜇-measure 0 for every automorphism invariant Keisler measure 𝜇 and (ii) a definable group 𝐺 in a simple theory such that 𝐺 is not definably amenable, i.e. there is no translation invariant Kei...
