Monday, April 16, 2012, from 4 to 5:30pm
East Hall, room 2866

Speaker: Andreas Blass (University of Michigan)

Title: Partition Theorems and Ultrafilters Part 4

Abstract:

I’ll discuss a forcing notion that adjoins an ultrafilter that (1) is not a P-point, (2) has the strongest square-bracket partition property consistent with not being a P-point, and (3) is not a sum of other ultrafilters.
