Leave the lunch box at home - the "Felleskollokvium" is back.

Atmospheric and climate sciences have a stronghold in Oslo among the four institutions University of Oslo, the Meteorological Institute, CICERO and NILU. This joint seminar invites renowned international experts to contribute to an informal series of lectures, meant to create interaction with the Oslo atmospheric and climate science community on recent highlights and analysis in the field. All seminars will be held on Thursdays (Noon -1pm) and lunch (sandwiches) will be served on a “first-come-first-served”-basis.

Prof. Masaki Izumi, Kyoto University, Japan, will give a talk with title:

The classification of poly-Z group actions on Kirchberg algebras

Abstract: We completely classify outer actions of a poly-Z group G on any Kirchberg algebra A in terms of a principal Aut(A x K)-bundle over the classifying space BG. This is joint work with Hiroki Matui.

Becky Armstrong, University of Sydney, Australia, will give a talk with title:

Simple graph algebras

Abstract: Since their introduction twenty years ago, C*-algebras associated to directed graphs have become a popular tool for investigating various classes of C*-algebras, because analytical properties of these C*-algebras depend on much simpler combinatorial properties of the underlying graphs. One such analytical property is simplicity, which plays a fundamental role in the classification program for C*-algebras. In this talk I will first recall the characterisation of simplicity for directed graph C*-algebras. I will then describe the results of my PhD research, in which I characterise simplicity of twisted C*-algebras of topological higher-rank graphs in terms of the underlying graphical and cohomological data. These C*-algebras are constructed using groupoid techniques for the purpose of this simplicity characterisation, but I will also briefly describe two product-system models for twisted C*-algebras of topological higher-rank graphs. (This is joint work with my PhD supervisors, Nathan Brownlowe and Aidan Sims.)

Geoff Nicholls (Department of Statistics, University of Oxford) and Idris Eckley (Mathematics and Statistics, Lancaster University) will both give a talk on September 17th, at 13:45 and 14:45, respectively, in the Seminar Room 819, Niels Henrik Abels hus, 8th floor.

This Academic Catwalk features exciting academic projects from three Nordic countries illustrating the rich and broad research milieus and their motivation to advance their ideas into innovations for patients.

We will have a “mingle” meeting. There will be updates from Kristine and Per on the running of the institute. But fear not, there will also be plenty of time for informal chat and eating of cake. All are welcome to the lobby on the first floor.

Bill Forman, CfA - Harvard

All who want to join the application process for funding of interdisciplinary research groups – convergence environments – have to join at least one  workshop in September. The registration deadline is 22 August.

Paolo Vidoni (Department of Economics and Statistics, University of Udine) will give a talk on September 4th at 14:15 in the Seminar Room 819, Niels Henrik Abels hus, 8th floor.

Title: How the fingerprint of past volcanic eruptions extracted from ice cores reveals their footprint on global climate

Speaker: Michael Sign (PSI/UiO)

The Mahowald invariant is a method for constructing nontrivial classes in the stable homotopy groups of spheres from lower dimensional classes. I will introduce this construction and recall Mahowald and Ravenel's computation of the Mahowald invariant of 2^i for all i . I'll then introduce motivic and equivariant analogs of the Mahowald invariant, outline the computation of the generalized Mahowald invariants of 2^i and \eta^i for all i , and discuss the relationship between these generalized computations and exotic periodicity in the equivariant and motivic stable homotopy groups of spheres.
