Dynamical Ideals of Topological Spaces

Justin Young ⟨jyoung3@ufl.edu⟩

Abstract:

Joint work with J. Zapletal

A dynamical ideal consists of a group acting on a set, along with an ideal that is invariant under the group action, and we can use dynamical ideals to obtain models of choiceless set theory. We focus on dynamical ideals where the underlying set is taken to be a topological space and the acting group is the group of homeomorphisms and look at how dynamical properties of the space correspond to fragments of AC in the associated model of set theory, along with particular examples.
