Abstract
The elliptic genera of the K3 surfaces, both compact andnon-compact cases, are studied by using the theory of mocktheta functions. We decompose the elliptic genus in termsof the $\mathcal{N}=4$ superconformal characters atlevel-$1$, and present an exact formula for thecoefficients of the massive (non-BPS) representations usingPoincaré–Maass series.
