K3 surfaces are examples of certain complex surfaces, which have fascinated mathematicians for almost two centuries. Quite recently, physicists have observed the phenomenon of Mathieu Moonshine. This phenomenon appears to relate a geometric invariant of K3 surfaces, the elliptic genus, to a large, finite group, the Mathieu group M24.
In this talk, we give an overview on the Mathieu Moonshine phenomenon and the quest for its explanation.
