Properly ergodic structures

Nathanael Ackerman, Cameron Freer, Alex Kruckman +1

We consider ergodic $Sym (N)$ -invariant probability measures on the space of $L$ -structures with domain $N$ (for $L$ a countable relational language), and…

Countable infinitary theories admitting an invariant measure

Nathanael Ackerman, Cameron Freer, Rehana Patel

Let $L$ be a countable language. We characterize, in terms of definable closure, those countable theories $Σ$ of $L_{ω_{1}, ω} (L)$ for which there exists an $S_{\infty}$ -inva…
