Code

WeilRep is Sage code for calculations with vector-valued modular forms for Weil representations, Jacobi forms, theta lifts and Borcherds products.
Download it from GitHub. See the readme for an explanation of how to use it.

• Here is code for working with eta products. It computes the q-series of an eta product and tries to identify an eta product from a q-series.
• Here is code for computing exact values of Dedekind zeta functions for totally real number fields.
• Here is code that attempts to split hyperbolic planes off of an even lattice.
