Guest lectures and seminars - Page 168

I'll review some basic ideas about topological Andre-Quillen theory and how it relates to E-infinity cell structures. As applications I'll discuss a new approach to calculating TAQ for HF_p and HZ, and various other recent results. These make heavy use of Dyer-Lashof operations and the coaction of the dual Steenrod algebra.   

This term the seminar will take place in Room GA 06 7166 in Ole-Johan Dahls hus. 

Time: Thursday 10.15 - 12.00

Access to the seminar room is restricted, and requires a university identity card with right of access encoded.

Active participants with new UiO identity cards should contact Dag Normann in order to obtain access.

Occasionally, we will meet in B62 in NHA.

Yusuke Isono  from the University of Tokyo will give a talk with title: Strong solidity of II_1 factors of free quantum groups

Abstract:

We generalize Ozawa's bi-exactness to discrete quantum groups and give a new sufficient condition for strong solidity, which implies the absence of Cartan subalgebras. As a corollary, we prove that II_1 factors of free quantum groups are strongly solid. We also consider similar conditions on non-Kac type quantum groups, namely, non finite von Neumann algebras.

This years Skolem Lecture will be by Peter Aczel from The University of Manchester:

The Structure Identity Principle in Set Theory and Type Theory.
