Humbert Surfaces and Isogeny Relations
In this talk, we present methods for computing Humbert surface equations and isogeny relations using Fourier expansions of Siegel modular forms. Both provide improvements to the running time of the CRT algorithm for computing Igusa class polynomials, which we illuminate with an example.
