Jacobi forms of theta type

Number Theory 2017-05-19 v2

Abstract

Let LL be a positive definite even lattice. We introduce theta type Jacobi forms and construct three towers of Jacobi forms with a particular easy pullback-structure. We use theta type Jacobi forms to explain the existence of a cusp form of weight 24 with respect to the irreducible root lattice D4D_{4} which is based on additional symmetries of the Coxeter diagram.
