08.03.2023 15:00 - 16:30

Juris Steprāns (York U, CA)

I will report on joint work with Dilip Raghavan solving a question of Blass about whether the existence of many selective ultrafilters implies the existence of Milliken-Taylor ultrafilters. The first part of the talk will provide the historical context of what was known in the mid 80s that prompted Blass to ask his question. The second part will discuss the key technical advance in our argument.

Students at Uni Wien are required to attend in person.
