S. Braunfeld, J. NeÅ¡etÅil, P. Ossona de Mendez

We show that given a monadically stable theory $T$ , a sufficiently saturated $M ⊨ T$ , and a coherent system of probability measures on the $I ¨ $ -algebras generated by…

When invariance implies exchangeability (and applications to invariant Keisler measures)

Samuel Braunfeld, Colin Jahel, Paolo Marimon

We study the problem of when, given a countable homogeneous structure $M$ and a space $S$ of expansions of $M$ , every $Aut (M)$ -invariant probability measure on $S$ is exch…
