Title:
On a set of Fourier coefficients which determine all Siegel cusp forms of degree two

Abstract: In this talk we first recall some basic facts about Siegel cusp forms of degree two. Then we present a particular set of integral, positive-definite, diagonal matrices A, and show that all such Siegel cusp forms are completely characterized by the Fourier coefficients indexed by the matrices in A.
