We explain how motivic categories with reasonable properties for arbitrary schemes can be constructed. A crucial property used for the construction is base change for a motivic Eilenberg-MacLane spectrum over Dedekind rings.   

Friday seminar by Adrian Dyer

Yabebal Tadesse Fantaye, postdoktor, Institutt for teoretisk astrofysikk, UiO.

Sara Ana Solanilla Blanco (Universitetet i Oslo) holder et seminar med tittelen: Forward prices as functionals of the spot path in commodity markets modeled by Lévy semistationary processes

Jan Fredrik Bjørnstad (SSB and Department of Mathematics, UiO) will talk about

Extended likelihood approach to large-scale multiple testing

Prof. Naoki Itoh, Sophia University, Japan

Nicola Scafetta, ACRIM & Duke University, USA

Martin Licht (University of Bonn) will give a talk about

On equilibrated a posteriori error estimation for Nedelec-elements

CEES Extra seminar by Paul D. Taylor

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.

Friday seminar by John M. Pandolfi (NB: NOTE THE TIME)

In connection with the Dr.Philos. defense of André Rognes, the two opponents are invited to give seminar talks:

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

The Structure Identity Principle in Set Theory and Type Theory.

CEES Extra seminar by Matthieu Bagard

CEES Extra seminar by Walter Salzburger

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.
