Title: Fraenkel-Mostowski models revisited
</p>
<p class="ql-ed">
Abstract <br />
<p>A group action on a set, together with an invariant ideal on the set, is called a dynamical ideal. Each dynamical ideal is associated with a permutation model of set theory. I will isolate a couple of novel dynamical properties of ideals which translate into fragments of axiom of choice in the associated permutation model. There are many natural examples.</p>
