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.   

Friday seminar by Peter J. Fashing & Nga Nguyen

Eamon Michael Scullion, postdoktor, Institutt for teoretisk astrofysikk

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.

Erik Bédos will give a talk with title: On equivariant representations of C*-dynamical systems

Abstract:

Let \Sigma=(A, G, \alpha, \sigma) denote a unital discrete twisted C*-dynamical system. In our recent work with Roberto Conti (Rome), it has emerged that the so-called equivariant representations of \Sigma on Hilbert A-modules play an interesting role, complementing the one played by covariant representations. We will discuss some aspects of this notion and illustrate its usefulness in the study of the crossed products associated with \Sigma.

Algebraic cobordism MGL was introduced by Voevodsky as an algebro-geometric analogue of complex cobordism MU: it is the universal oriented cohomology theory for smooth schemes. A fundamental result in homotopy theory is Quillen's identification of the homotopy groups of MU with the Lazard ring. Voevodsky conjectured an analogous result for MGL, and his conjecture was recently proved for regular schemes of characteristic zero and up to p-torsion for regular schemes of charateristic p>0. I will explain Voevodsky's conjecture and sketch the proof in these cases.
