CPT Student Seminar: From Elliptic Genus to Moonshine

Presented by Xin Tang, Durham University

15 June 2015 17:00 in OC218

In this talk I will introduce Moonshine from a physical point of view by introducing the partition function of different (super-)conformal field theories. The non-trivial topological invariant partition function, i.e. elliptic genus will be introduced when we consider N=2 and N=4 superconformal algebras. I will then decompose the elliptic genus of K3 surface in terms of small N=4 superconformal characters and show how to find the Mathieu moonshine explictly from the decomposition.

A gathering of mathematicians from the CPT group with physicists from IPPP, we meet to discuss our work in a relaxed and friendly environment.
