Predavač: Jeffrey Bergfalk, University of Vienna
 
Naslov predavanja: CONDENSED MATHEMATICS AND INFINITARY COMBINATORICS
 
Apstrakt:
Around 2019, Dustin Clausen and Peter Scholze undertook the systematic development of an approach to "doing algebra with objects carrying a topology" which they term *condensed mathematics*, work which actively continues today. After a brief introduction to this approach, we survey some of its connections to infinitary combinatorics, both via derived functor computations and set theoretic forcing. Connecting these two prongs in turn is an analysis of Whitehead`s problem (does Ext(A,Z)=0 imply that A is free?) in the setting of condensed abelian groups. This work is joint with Chris Lambie-Hanson and Jan Saroch.
