Graded Riemann Spheres and two dimensional Conformal Field Theory

Informal Seminar Jasbir Nagi (DAMTP, Cambridge)

room 423
abstract:

Riemann Spheres are extremely useful as objects to build Conformal Field Theory on. Graded Riemann Spheres turn out to be extremely useful in the study Superconformal Field Theory. In particular, I will look at the conformal algebras of vector fields that arise, and their associated primary fields that are given by the geometry. I will also look at some peculiarities that arise in N=4 theories.
