Judith Packer, University of Colorado (Boulder), will give a talk with title "Noncommutative solenoids and their projective modules"

Abstract: ``Noncommutative solenoids" are certain twisted group $C^*$-algebras, where the groups in question are countably infinitely generated; these algebras can also be generated as direct limits of rotation algebras.  From examining the range of the trace of the $K_0$-groups of the noncommutative solenoids, their finitely generated projective modules can be constructed. We also discuss a way to construct Morita equivalence bimodules between noncommutative solenoids that goes back to work of M. Rieffel, with the new wrinkle of $p$-adic analysis appearing. This work is joint with F. Latr\'emoli\'ere.

Professor Madan L. Puri (Indiana University) holder et seminar med tittelen: Asymptotic Normality, Rates of Convergence, and Large Deviation Probabilities for a Broad Class of Statistics.

Abstract: We will begin by reviewing and constructing power operations in the familiar setting of chain complexes. In stable homotopy, these operations help distinguish different geometric objects. These operations are also the residue of a rich homotopical structure. We will also define such structure and explain its role in stable homotopy theory. Specifically, we will consider what structure on a filtration might give rise to power operations in the associated spectral sequence, if time allows. This first talk will be accessible to graduate students.    Such power operations also act on the homotopy of highly structured ring spectra. We will compute these operations on relative smash products using the Kunneth spectral sequence. We will interpret the homotopy of these relative smash products and the algebra of operations in terms of different realizations of highly structured DGAs. We will also discuss the relation to the relevant notion of cotangent complexes.

Bas Jordans (UiO) will give a talk with title: Real dimensional spaces in noncommutative geometry

Abstract:

In noncommutative geometry geometric spaces are given by spectral triples. In this talk we consider a generalisation of these spectral triples to semifinite spectral triples. In analogy to the classical case it is possible to construct the product of two semifinite spectral triples. We will construct this product and derive properties thereof. Also we will describe for each z\in(0,\infty) a semifinite spectral triple which can be considered as having dimension z. As an application these "z-dimensional" semifinite triples will be used for two regularisation methods in physics.

Dr. Ujjwal Koley from University of Würzburg, is going to talk about Operator splitting methods for Korteweg de-Vries (KdV) equation

Ilia Musco will give a seminar.

Muligheter for samarbeid med DHI innen forskning, PhD og master-prosjekter.

David Ruiz Baños (Universitetet i Oslo) holder et seminar med tittelen:  Computing Greeks without Derivatives

The symposium is a follow-up of two highly successful previous symposia, held 14-15 October 2008 in the Norwegian Academy in Oslo and 1-2 November 2010 in RSE in Edinburgh. Topics of this year's symposium include: internal waves, ocean surface waves and tsunamis reflecting the activities in the current research projects of the Norwegian and Scottish groups.

Oleg Reichmann (ETH Zurich) holder et seminar med tittelen: Time and space inhomogeneous models in option pricing

Professor G. Scandolo (University of Verona and Firenze) holder et seminar med tittelen: Assessing Financial Model Risk

We explain how motivic categories with reasonable properties for arbitrary schemes can be constructed. A crucial property used for the construction is base change for a motivic Eilenberg-MacLane spectrum over Dedekind rings.

Jan Fredrik Bjørnstad (SSB and Department of Mathematics, UiO) will talk about

Extended likelihood approach to large-scale multiple testing

Martin Licht (University of Bonn) will give a talk about

On equilibrated a posteriori error estimation for Nedelec-elements

I'll review some basic ideas about topological Andre-Quillen theory and how it relates to E-infinity cell structures. As applications I'll discuss a new approach to calculating TAQ for HF_p and HZ, and various other recent results. These make heavy use of Dyer-Lashof operations and the coaction of the dual Steenrod algebra.
