Maths HEP Lunchtime Seminars: Umbral Moonshine and K3 Surfaces
9 May 2014 13:00 in CM221
In this talk I will first discuss the "umbral moonshine" relating special mock modular forms to representations of special finite groups. This novel type of moonshine is constructed using the data of the Niemeier lattices. Afterwards I will discuss its relation to the elliptic genus of K3 in the context of string theory and conformal field theory. This talk will be based on joint work with J. Duncan, J. Harvey and S. Harrison.
