Eigenvalues and Fourier coefficients of degree two Siegel eigenforms constructed from Igusa theta constants

Research output: Contribution to journalArticlepeer-review

Abstract

We prove multiplicative relations among certain Fourier coefficients of degree two Siegel eigenforms constructed from Igusa theta constants with half-integral characteristics. We also provide simple relations between their eigenvalues and their Fourier coefficients.
