Some relations on Fourier coefficients of degree 2 Siegel forms of arbitrary level

21 Feb 2017 · Walling Lynne H. ·

We extend some recent work of D. McCarthy, proving relations among some Fourier coefficients of a degree 2 Siegel modular form $F$ with arbitrary level and character, provided there are some primes $q$ so that $F$ is an eigenform for the Hecke operators $T(q)$ and $T_1(q^2)$.
