Karl Ove Moene, Professor - Centre for the Study of Equality, Social Organization, and Performance

Abstract: In the classification program for C*-algebras some of the usual assumptions put on the algebras are that they are simple or have at most have finitely many ideals. We often also want algebras that have real rank 0. In this talk we will discuss how to classify certain graph algebras with uncountably many ideals and without real rank 0. There will be examples and applications. Joint work with S. Eilers, G. Restorff, and E. Ruiz

ESOP seminar. Vincent Somville is a senior researcher at the Christian Michelsen Institute (CMI). He will present a paper entitled "Saving by Default: Evidence from a Field Experiment in Rural India", written jointly with Lore Vandewalle.

K3 surfaces seminar: The moduli spaces of polarized K3 surfaces

Abstract: There are many interesting examples of groups acting on trees, arising in various fields (e.g. combinatorial group theory, number theory, geometry). When a group acts on a tree, it necessarily also acts on the boundary of the tree, a (totally disconnected) compact Hausdorff space.  The C*-algebras obtained from the crossed product construction include many fundamental examples.  I will describe methods for analyzing such crossed products, developed in joint work with Nathan Brownlowe, Alex Mundey, David Pask and Anne Thomas.

Manuela Zucknick (Dept. of Biostatistics, UiO) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.

ESOP seminar. Paolo Piacquadio is Assistant Professor of Economics at UiO. He will present the paper "A Fairness Justification of Utilitarianism".

K3 surfaces seminar: Endomorphism fields and Mumford¨CTate groups II

By Mikael Fortelius

Shuo-Wang Qiao, Associate Professor - Department of Immunology

Abstract: In this follow-up talk, I shall outline how the boundary quotient diagram may be useful for K-theoretic considerations. We start with the diagram within the context of integral dynamics, and then speculate about potentially promising directions of generalizations.

ESOP workshop. Richard Freeman holds the Herbert Ascherman Chair in Economics at Harvard University.

ESOP invites to a public lecture with professor Richard Freeman from Harvard University. Freeman will discuss how a combination of Shared Capitalism and Pension Fund Socialism can become a viable and more equitable new economy.

ESOP seminar. Astrid Marie Jorde Sands?r is PhD-student at UiO. She will present a paper entitled "Grade Variance".

The main attractions of this Mingle meeting will be Luc Rouppe, who will talk about his Toppforsk (and some recent news from the NOT), and Sven Wedemeyer who will talk about ALMA.

Otherwise there will be updates from Kristine and Viggo 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.

Zebrafish embryos: a useful tool for the study of nanoparticle behavior in real time in a vertebrate

K3 surfaces seminar: Endomorphism fields and Mumford¨CTate groups

Abstract: In this follow-up talk, we shall review the results on the structure of KMS states from the case studies of - the ax+b semigroup over the natural numbers (Laca-Raeburn and Brownlowe-an Huef-Laca-Raeburn), - integer dilation matrices (Laca-Raeburn-Ramagge), - self-similar actions (Laca-Raeburn-Ramagge-Whittaker), and - Baumslag-Solitair monoids (Clark-an Huef-Raeburn) from the perspective of the boundary quotient diagram for the respective right LCM semigroups. We will also discuss (to some extent) similarities and differences of the proofs among these cases.

Thore Egeland (NMBU) will give a seminar in the lunch area, 8th floor Niels Henrik Abels hus at 14:15.
