Kristian Ranestad, UiO, gives the Seminar in Algebra and Algebraic Geometry:

Variety of sums of powers of bihomogeneous forms

Peter Lumsdaine, Stockholms Universitet, vil gi to seminarinnlegg, det ene på logikkseminaret.

Piotr Soltan (University of Warsaw) will give a talk with title: Subgroups of quantum groups, the center and inner automorphisms

Tobias Erhardt (Technische Universität, München) will give a seminar in the lunch area, 8th floor N.H. Abel's House at 14:15 November 24th.

Arnaud Brothier, Vanderbilt University (USA) will give a talk with title: Analytic properties for subfactors

Abstract:

I will discuss analytic properties for groups and their generalizations to subfactors, standard invariants, and certain tensor categories.

I will present a class of subfactor planar algebras that are constructed with a group acting on a bipartite graph.

I will show that if the group satisfies a given approximation property (such as amenability, Haagerup property, or weak amenability), then the subfactor planar algebra satisfies it as well.

I will exhibit an infinite family of subfactor planar algebras with non-integer index that are non-amenable, have the Haagerup property, and have the complete metric approximation property.

CEES Extra seminar by Laura Nuño de la Rosa

Rough paths and rough partial differential equations

Friday seminar by Marius Roesti from University of Basel (Switzerland) and University of British Columbia (Canada)

Robert Jenssen (University of Tromsø) will give a seminar in the lunch area, 8th floor N.H. Abel's House at 14:15 November 10th.

The Tuesday statistics seminar on November 10th at the Mathematics department is unfortunately canceled.

PIV investigation of the flow structures developing in a parallel valves Diesel engine cylinder during the intake stroke.  

In this talk I will present the Real algebraic K-theory construction of Hesselholt and Madsen, and discuss some on-going joint work with Ib Madsen. Real algebraic K-theory is a functor that to a ring A with anti-involution associates a genuine C_2-equivariant spectrum KR(A). Here C_2 denotes the cyclic group of order two. The underlying spectrum of KR(A) has the homotopy type of K(A), the usual K-theory space of A in the sense of Quillen, and the C_2-fixed point spectrum is weakly equivalent to the Hermitian K-theory of A. I will talk about generalizations of known theorems for algebraic K-theory to KR, including delooping results, "fundamental" theorems and group completion.

Håkon Robbestad Gylterud, Stockholm Universitetet

Alfons van Daele (Leuven) will give a talk with title: The Haar measure on quantum groups

Abstract: At this moment, there is no theory of locally compact quantum groups with axioms from which one can prove the existence of the Haar weights. In general, the existence is part of the axioms. There are however a few cases where the existence can be proven. This is true for compact quantum groups and for discrete quantum groups. We will discuss some aspects of these proofs and see which of them are useful in the general case.
