- Abstract: We derive an upper bound for (the sum corresponding to an isotropic subgroup of) the constant terms of a weight-0 vector-valued modular form that transforms under the Weil representation, based on a pairing argument with weight-2 vector-valued Eisenstein series.
- As an application we prove a vertex algebra analogue of the remarkable result by Conway, Parker and Sloane (and Borcherds) that there is a bijection between the deep holes of the Leech lattice and the 23 Niemeier lattices with roots.
