When Where Who Title (Click for abstract)
Wed 17 Mar 2010 11:00 MB, room C Prof. Dorothea Bahns (University of Goettingen) The Shuffle Algebra and String Quantization in d dimensions
Abstract. I will review a purely algebraic approach to the quantization of strings, e.g. minimal surfaces, based on the deformation of a certain Poisson algebra. The elements of this algebra are invariant under changes of the string's parametrization and the formalism is consistent in any dimension of the embedding space. This is in contrast to the ordinary approach to string quantization which is based on methods from conformal field theory and requires fixing the dimension to a critical value (26 in the model discussed in the talk).
Wed 17 Mar 2010 14:30 MB, room D Prof. V. Dragovic (Belgrade) Kowalevski top, Darboux coordinates and discriminant separability
Abstract.
Thu 18 Mar 2010 14:30 MB, room D Prof. Bernardo Uribe (Universidad de los Andes, Bogotá) Symmetries of Exact Courant Algebroids
Abstract. I will present the different descriptions used to understand an exact Courant algebroid, and I will explain how the derivations of an exact Courant algebroid become a dgla whose "derived" bracket recovers the Courant bracket. I will finish by stating some results relating the symmetries with twisted equivariant cohomology.

When Where Who Title (Click for abstract)
Thu 11 Mar 2010 13:30 MB, room C A. Guazzi and M. Tommasini (SISSA) Some basic concepts of Algebraic Quantum Field Theory
Abstract. This is a reading seminar about the paper

J.E. Roberts, G. Roepstorff, "Some Basic Concepts of Algebraic Quantum Field Theory", Commun. Math. Phys. 11, 321-338 (1968).

Concepts from the theory of C*-algebras are applied to relativistic quantum field theory; in particular, to the structure of superselection sectors.

This will be in fulfilment of the requirements for the course "Introduction to C*-algebras".
Tue 9 Mar 2010 11:00 MB, room C Dr. Jyotishman Bhowmick (ICTP) Quantum isometry groups II
Abstract.
Mon 8 Mar 2010 14:30 MB, room D Prof. Tamara Grava (SISSA) Deift-Zhou method of steepest descent (2nd part)
Abstract. no abstract available.
Fri 5 Mar 2010 11:00 MB, room C Dr. Jyotishman Bhowmick (ICTP) Quantum isometry groups
Abstract.
Thu 4 Mar 2010 16:00 MB, room D Prof. Julius L. Shaneson (University of Pennsylvania) Invariants of manifolds and stratified spaces
Abstract. A basic problem in geometric topology is to try to classify spaces - manifolds, varieties, stratified spaces - by computing suitable invariants, especially characteristic classes. A basic problem in combinatorics/analysis/number theory is to sum functions over integral lattice points in a region. This talk concerns the first problem and how the study of the relevant invariants for toric varieties provides one approach to the second problem.
Thu 4 Mar 2010 14:30 MB, room D Prof. Antonella Grassi (University of Pennsylvania) Toric Weierstrass models
Abstract. We define a "natural" toric Weierstrass model for an elliptic variety X which is a hypersurface in a Fano toric variety and discuss some properties.

Abstract. no abstract available
Wed 10 Feb 2010 15:30 MB, room C Prof. Ian D. Marshall (Loughborough University) Poisson structure associated to differential and difference operators with the Toda lattice and KdV as examples
Abstract. I will describe a Poisson structure on the space of curves in R^n from which a series of Poisson structures on several associated spaces may be obtained by Poisson symmetry arguments. Amongst these spaces one may find differential operators and difference operators and their respective reductions. Most of the talk will involve the concrete cases n=2,3, for which the natural examples are the KdV and the Toda lattice. The construction is a simple application of the theory of Poisson Lie groups and it is intended that it will serve as an illustration of that subject, accessible to non-specialists.
