Query: Automorphic Black Hole Entropy   Over the past few years the understanding of the microscopic theory of black
hole entropy has made important conceptual progress by recognizing that the
degeneracies are encoded in partition functions which are determined by higher
rank automorphic representations, in particular in the context of Siegel
modular forms of genus two. In this brief review some of the elements of this
framework are highlighted. One of the surprising aspects is that the Siegel
forms that have appeared in the entropic framework are geometric in origin,
arising from weight two cusp forms, hence from elliptic curves.
