Friday seminar by Camilla Stoltenberg

Professor Nikolai ?stgaard, Professor at Dept. of Physics and Technology, University of Bergen

Bjørn Jahren fortsetter seminaret om 4-mangfoldigheter i uke 8

(ikke seminar i uke 7).

Friday seminar by Daniele Silvestro

Jorrit Leenaarts, post doc., Institutt for teoretisk astrofysikk, UiO

Å bruke numerikk i undervisningen er enklere enn du tror, og kan føre til bedre forståelse av fysiske fenomener og være nyttig i din egen forskning og formidling. I dette foredraget vil vi vise hvor lite som skal til for å komme i gang.

Kollokviet er beregnet på undervisere, men vil også være interessant for alle som vil vite mer om numeriske metoder i undervisning, forskning og formidling.

Extra seminar by Audun Rikardsen

Marcus K. V. Eriksson (Universitetet i Oslo) holder et seminar med tittelen: A valuation model with minimal and maximal constraints for swing options.

Roberto Conti, Universita La Sapienza (Rome), Italy, will give a talk with title: The dark side of the Cuntz algebras

Abstract: We provide an overview of our recent work on the automorphism group of Cuntz algebras and discuss a number of open problems. (Joint work with J.H. Hong and W. Szymanski).

Benjamin Holcblat (Department of Financial Economics, BI) will talk about

A Classical Moment-Based Approach with Bayesian Properties: Econometric Theory and Empirical Evidence from Asset Pricing

Extra seminar by Henkjan Honing (the Darwin Day vorspiel lecturer!)

Friday seminar by Sarah Randolph (NOTE THE TIME AND VENUE)

Gunther Cornelissen, Utrecht University (The Netherlands) will give a talk with title "Dynamical systems and point counting"

Abstract: Counting the points of a curve over finite fields doesn't determine the curve up to isomorphism; this is analogous to the famous fact that you cannot "hear the shape of a drum". I will show how to remedy this by counting points in a weighted way (namely, using abelian L-series). The method of proof is through the theory of dynamical systems, and - curiously - arose from a study of a quantum statistical mechanical system.  

Makoto Yamashita, p.t. University of Copenhagen, will give a talk with title "Tannaka-Krein duality of quantum homogeneous spaces"

Abstract: We study ergodic actions of compact quantum groups on operator algebras  (quantum homogeneous spaces) from the categorical point of view. The language of Rep(G)-module C*-categories gives a reconstruction theorem of quantum homogeneous spaces, which also captures the equivariant Morita equivalence and the equivariant homomorphisms.  For the case of quantum SU(2), the universality of Rep(SUq(2)) allows us to obtain a combinatorial description of quantum homogeneous spaces and their properties. Based on joint work with Kenny De Commer (arXiv:1211.6552, arXiv:1212.3413).  

Professor i anestesi og sedasjon James Roelofse MB ChB, MMed (Anaes), PhD (Anaes) leder avdeling for anestesi og sedasjon ved University of the Western Cape, Syd-Afrika vil holde gjesteforelesning tirsdag 5.februar med tittelen Transmucosal drugs in sedation practice. 

Forelesningen vil gi en oversikt over transmucosale sedasjonsteknikker illustrert med kliniske eksempler av pasienter med behandlingsvegring, og er ?pen for alle interesserte.

Bjørn Jahren fortsetter seminaret om 4-mangfoldigheter.

Friday seminar by Bernt-Erik S?ther

Professor Erwan Rauwel, University of Tallinn, Tartu College, Estonia

Rama Cont (Imperial College) holder et seminar med tittelen: Functional Ito calculus and functional Kolmogorov equations

Magnus Dahler Norling, UiO, will give a talk with title: The K-theory of some reduced inverse semigroup C*-algebras

Abstract: We use a recent result by Cuntz, Echterhoff and Li about the K-theory of certain reduced C*-crossed products to describe the K-theory of C*_r(S) when S is an inverse semigroup satisfying certain requirements. A result of Milan and Steinberg allows us to show that C*_r(S) is Morita equivalent to a crossed product of the type handled by Cuntz, Echterhoff and Li. We apply the results to graph inverse semigroups and the inverse semigroups of one-dimensional tilings.

Michael Scheuerer will talk about (Institute of Applied Mathematics, Heidelberg University)

Statistical post-processing of weather forecasts: The importance of spatial modeling

Dette semesteret arrangerer vi et seminar om 4-mangfoldigheter, et felt som burde interessere både topologer og algebraiskgeometere. Dessuten, siden vi nå er i samme avdeling, bør vi jo ha noe felles aktivitet. Et overordnet mål er å studere komplekse flater opp til diffeomorfi. Det konkrete programmet vil bli til underveis, men emner vi regner med å komme innom inkluderer - Topologisk klassifikasjon av enkeltsammenhengende, kompakte   4-mangfoldigheter (Freedman) - Donaldsons teorem om snittformen til differensiable 4-mangfoldigheter - Enriques-Kodaira klassifikasjon av komplekse flater - Seiberg-Witten teori.

Vi starter opp mandag 28. januar 1415-1600 i B70 med at Bjørn snakker om snittformen og den topologiske teorien. Bjørn Jahren og Geir Ellingsrud

Program for the seminar in Logic, Spring 2013
