Speaker: **Henry Klatt** (ISU)

Both positions, called the universe and multiverse views, have their advocates, who, to find evidence for their positions, have produced a large amount of deep and interesting mathematics. In this series of talks, we will look at some of the mathematics that has come out of the multiverse camp. Topics include a natural model for the multiverse axioms, the modal logic of forcing, and set theoretic geology.

This is a continuation of the April 6th presentation.
