Workshop on Interfaces and Wall-crossings

30.11.2009 – 04.12.2009

This ASC workshop aims to bring together experts interested in the various aspects of Interfaces and Wall-crossings, two topics that have arisen in several contexts in supersymmetric QFT and string theory recently.

Although the two topics are currently distinct, there are indications that they may be related. The aim of the workshop is to bring together people interested in either of these subjects, and to explore their possible connections and applications.

There is no registration fee, and everybody is welcome to attend the workshop.

The organizers are: Costas Bachas, Ilka Brunner, Christian Römelsberger

All talks will take place in the ASC lecture room 348/349, 3rd floor, Theresienstr. 37 (how to reach us).
