The compact action realization problem

I will discuss recent progress concerning the problem of realizing countable Borel equivalence relations as orbit equivalence relations of continuous actions of countable groups on compact metrizable spaces. 

This is joint work with Josh Frisch, Forte Shinko and Zoltan Vidny\'{a}nszky,
