Abstract

If L ⊆ ℤn is a lattice of finite index, let , where the sum is over all lattices L′ with LL′ ⊆ ℤn. Using the automorphic theory of GL2n, a generalization of the Voronoi-Oppenheim summation formula is proved for these generalized divisor functions. Bessel distributions and Hankel transforms associated with the Shalika model for the degenerate principal series representations of GL2n(ℝ) are principal tools.
