Title: Treeability and planarity in measured group theory

Abstract: A group G is called strongly treeable if the orbit equivalence relation associated to any free probability measure preserving action of G can be measurably structured by trees. I will discuss joint work with Clinton Conley, Damien Gaboriau, and Andrew Marks in which we show that all groups with planar Cayley graphs are strongly treeable. This provides the first examples of groups with one end which are strongly treeable.
