Michigan Logic Seminar

There will be a logic seminar TOMORROW, Wednesday, December 7, from 4 to 5:30, in 3096 East Hall.

Peter Krautzberger will continue to speak on “Minimal ideals in beta(N)”.

Abstract:

Continuing the introductory talk on idempotent ultrafilters, I will try to give an introduction into the algebraic structure of the semigroup $beta mathbb{N}$, in particular the smallest two-sided ideal and minimal left (right) ideals.

As last time, I will compile some reading materials ahead of time so as to facilitate discussion.

This talk will be video recorded and available at vimeo.com/pkrautzberger.

There will also be a Google+ Hangout during the seminar via Peter Krautzberger.
