Sergej Monavari: Counting instantons by counting boxes

Salle 318 (IMB) Salle 318 (IMB)

A major modern problem in topological string theory is the studying of instanton moduli spaces, and their associated partition functions. We will try to explain the mathematical counterpart of this problem (Donaldson-Thomas

Dimitri Gourevitch: Combinatorics on Reflection Equation algebras

Salle 318 (IMB) Salle 318 (IMB)

Reflection Equation Algebras (without parameters) are very remarkable objects. They admit introducing q-analogs of certain symmetric functions and quantum versions of some classical formulae of combinatorics:  Capelli, Frobenius and others. I plan

Wolfgang Wieland: Quantum Geometry of the Light Cone

Recently, I introduced a non-perturbative quantization of impulsive gravitational null initial data. In this talk, I present the key results established thus far. The starting point is the characteristic null initial problem for tetradic gravity

Yoshihisa Saito: On elliptic root systems and their applications

Salle 318 (IMB) Salle 318 (IMB)

In the middle of 1980's, motivated by study of singularity theories, K. Saito introduced the notion of "elliptic root systems". Roughly speaking, they are root systems with two null directions. Furthermore, he

Volker Betz: The effective mass of the polaron

Salle 318 (IMB) Salle 318 (IMB)

The polaron describes a charged particle moving in a polarizable medium. Due to the interaction with the medium, the particle appears to be heavier that it would be outside the medium. This

COLLOQUIUM David Krejčiřík « Is the optimal rectangle a square? « 

Salle René Baire (IMB) Salle René Baire (IMB)

Speakers: David Krejčiřík (Czech Technical University in Prague)We give a light talk on optimality of shapes in geometry and physics. First, we recollect classical geometric results that the disk has the largest area (respectively,
