Abstract

We review the properties of characters of the N=4 SCA in the context of a non-linear sigma model on K3, how they are used to span the orbits, and how the orbits produce topological invariants like the elliptic genus. We derive the same expression for the K3 elliptic genus using three different Gepner models (1, 2 and 4 theories), detailing the orbits and… (More)
