Title:
D-branes, categories and super-potential algebras

Speaker:
David Berenstein

Abstract:
I will describe some of the physics intuition that gives rise to a structure of categories of D-branes. I will then concentrate on the structure of the category of “point-like objects” near a singularity. This will use some examples of orbifolds and I will also show the concept of discrete torsion. I will then specialize further to situations that arise for the point-like branes that probe a Calabi-Yau singularity and use the physics intuition to show that one gets the notion of a “super potential algebra” and some of the properties they have for orbifolds.
