Abstract

In this paper we derive an explicit formula for the Hirzebruch-Mumford volume of an indefinite lattice of rank . If is an arithmetic subgroup and has signature , then an application of Hirzebruch-Mumford proportionality allows us to determine the leading term of the growth of the dimension of the spaces of cusp forms of weight , as goes to infinity. We compute this in a number of examples, which are important for geometric applications.
