High Energy Theory Seminar

In the beginning of my talk I will review some general facts about 3d-3d correspondence and describe how to construct 3d theory T[M_3] associated to a Seifert 3-manifold M_3. Then I will show how one can calculate the Casson-Walker invariant of M_3...

(Building on work by Sachdev, Ye, Parcollet and Georges) Kitaev has proposed a simple quantum mechanical model as a dual to an AdS_2 black hole. It would be nice to understand the bulk theory. (Is it local? Is there randomness? How is conformal...

I will survey some properties of the 6d (2,0) theories that can be determined using only their symmetries. In particular, I will discuss their anomalies, moduli spaces, ADE classification, and the relation to 5d super Yang-Mills.

I will introduce polynomial congruences and indicate why number theorists might care about them. I will then describe reciprocity laws which predict the number of solutions to a polynomial congruence in terms of discrete subgroups of Lie groups. The...
