Sandra Gran Stadniczenko (PhD student, AQUA)
Salvador Ortiz-Latorre (University of Oslo) is giving his inaugural lecture with the title: High order weak approximation of SDEs
This will be a colloqium-style talk, with pictures, about the classifying spaces and automorphism groups of manifolds, and the relation to surgery theory and algebraic K-theory.
Uni Fuskeland, PhD student, ITA
Andrea Hofmann (HBV) gives the Seminar in Algebra and Algebraic Geometry:
Minimal resolutions for projective models of K3 surfaces in rational normal scrolls
Literature used in the seminar are selected chapters in the book ?K3 Projective Models in Scrolls? by Trygve Johnsen and Andreas Leopold Knutsen.
Abstract: As has been observed by many authors, the Drinfeld double of the q-deformation of a compact Lie group can be regarded as a quantization of the complexification of the original Lie group. Using this point of view, I will discuss irreducible unitary representations of these Drinfeld doubles.

Geir Ellingsrud (UiO), gives the Seminar in Algebra and Algebraic Geometry:
Projective models of K3-surfaces II
The seminar takes place in the seminar room on the 9th floor of the computer science building.
Abstract: We discuss a way of constructing noncommutative projective manifolds as inductive and projective limits, generalizing the so-called Berezin quantization for ordinary compact K?hler manifolds. We first review the physical motivation for Berezin quantization and then discuss how the restriction to commutative manifolds limits the use of this quantization. We will also outline how our more general construction appears naturally in the study of the long-time limit of open quantum systems.
Ingrid Hob?k Haff (UiO, Dept. of mathematics) will give a seminar in the lunch area, 8th floor N.H. Abel's House at 14:15.

Introduksjon til K3-flater (etter Saint-Donat)
Bas Jordans will give a talk with title " Random walks on discrete quantum groups: convergence to the boundary"
Abstract:
For classical random walks there exist two boundaries: the Poisson boundary and the Martin boundary. The relation between these two boundaries is described by the so-called "convergence to the boundary". For random walks on discrete quantum groups both the Poisson boundary and Martin boundary are defined and a non-commutative analogue of convergence to the boundary can be formulated. However, no proof is known for a such a theorem. In the first part of the talk we will discuss the classical and quantum version of convergence to the boundary, explain how these are related and give an overview of what is known in general for the quantum case. In the second part we will discuss the boundary convergence for SUq(2) and for monoidally equivalent quantum groups.
