E11 extended spacetime and gauged supergravities

Seven-branes, Instantons and Supersymmetry

(University of Groningen)
Conformal Field Theories, BPS states and Geometry
Alberto Zaffaroni
(Univerisy di Milano-Bicocca and INFN, Italy)
Abstract:
I discuss some aspects of the conformal field theories obtained by placing D3 branes at conical singularities focusing on the rich interplay between the properties of the gauge theories and the geometry of the internal manifold. I discuss in particular the role of baryons, a character for counting all BPS baryonic operators and its geometrical interpretation.

Wetting and Minimal Surfaces
📍 London
Costas Bachas
(ENS Paris)
Abstract:
The phenomena of capillarity and (partial) wetting have been studied for two centuries, yet they continue to be of great current interest. After a brief historical review, I will discuss some recent results on the associated minimal-surface problem. In conclusion, I will draw some analogies with problems facing present-day string theory.
