Seminar organizer’s toolbox
Born 27 October 1947. Andreas Blass’s primary field of research is set theory, but he has also worked in other branches of logic (including recursion theory and topos theory), in theoretical computer science, and in finite combinatorics. Amid many excursions to other areas, he has always returned to ultrafilters, especially the combinatorial properties of ultrafilters on the natural numbers.
He received his Ph.D. from Harvard University in 1970, under the supervision of Frank Wattenberg, and he has been at the University of Michigan ever since, except for sabbaticals at Wisconsin, Penn State, and now the Fields Institute. For each of the last 10 years, he has spent part or all of the summer as a visiting researcher at Microsoft Research.
Recent and upcoming talks by Andreas Blass
Andreas Blass: Partition Theorems and Ultrafilters Part 5
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 Ppoint, (2) has the strongest squarebracket partition property consistent with not being a Ppoint, and (3) is not a sum of other ultrafilters. continue reading…

Speaker: Andreas Blass (University of Michigan)
Title: Ultrafilters and Partition Relations
Abstract:
I’ll finish the proof of the partition theorem for selectiveindexed sums of nonisomorphic selective ultrafilters. continue reading…

Monday, March 12, 2012, from 4 to 5:30pm
East Hall, room 2866
Speaker: Andreas Blass (University of Michigan)
Title: Partition Theorems and Ultrafilters
Abstract:
My longterm goal is to discuss a notion of forcing that produces an ultrafilter on the natural numbers that (1) is not a Ppoint but (2) has the strongest partition properties that are possible subject to (1). continue reading…
