Adam Skalski (IMPAN) will give a talk with title: Closed quantum subgroups of locally compact quantum groups and some questions of noncommutative harmonic analysis (based on joint work with Matt Daws, Pawel Kasprzak and Piotr Soltan)

Abstract: The notion of a closed subgroup of a locally compact group is a very straightforward concept, often featuring in classical harmonic analysis. I will discuss the possible extensions of this notion to the quantum setting, focusing on the comparison of the two definitions proposed by S. Vaes and S.L.  Woronowicz. I will describe some reformulations of these definitions and explain how they can beshown to be equivalent in many cases; I will also mention certain connections to other problems of quantum harmonic analysis.  

Nicolai Stammeier, Westfälische Wilhelms-Universität Münster, will give a talk with title: Product Systems of Finite Type for Certain Algebraic Dynamics and their C*-algebras

Abstract: Let P be a lattice-ordered semigroup with unit acting on a discrete, abelian group G by injective endomorphisms with finite cokernel. Building on the work of Jeong Hee Hong, Nadia S. Larsen and Wojciech Szymanski on product systems of Hilbert bimodules and their KMS-states, one can associate a product system to this dynamical system that turns out to be of finite type. Imposing two additional conditions on the dynamics, namely independence of the endomorphisms for relatively prime elements in P and exactness, we derive presentations of the Nica-Toeplitz algebra and the Cuntz-Nica-Pimsner algebra. Moreover, the latter has lots of nice descriptions and is shown to be a unital UCT Kirchberg algebra.  

Geir Ellingsrud fortsetter seminaret om 4-mangfoldigheter og  om elliptiske fibrasjoner.

Protima Raudwel, Researcher, SMN (Centre for Materials Science and Nanotechnology), UiO

CEES Extra seminar by Juan A. Bonachela from Levin Lab

I dette miniseminaret er det mye nytt å lære i relasjon til diabetes og metabolske sykdommer! Professor Juergen Eckel fra German Diabetes Center, Heinrich-Heine-Universität, Düsseldorf, vil snakke om sine siste forskningsresultater. Fire stipendiater/postdoktorer vil dessuten presentere sin forskning.

Geir Ellingsrud fortsetter seminaret om 4-mangfoldigheter og denne gangen snakker han om elliptiske fibrasjoner.
