Hecke operators on half-integral weight Siegel Eisenstein series

We construct a basis for the space of half-integral weight Siegel Eisenstein series of level 4N where N is odd and square-free. Then we restrict our attention to those Eisenstein series generated from elements of \(\Gamma_0(4)\), commenting on why this restriction is necessary for our methods. We di...

Summary:We construct a basis for the space of half-integral weight Siegel Eisenstein series of level 4N where N is odd and square-free. Then we restrict our attention to those Eisenstein series generated from elements of \(\Gamma_0(4)\), commenting on why this restriction is necessary for our methods. We directly apply to these forms all Hecke operators attached to odd primes, and we realize the images explicitly as linear combinations of Siegel Eisenstein series. Using this information, we diagonalize the subspace of Eisenstein series generated from elements of \(\Gamma_0(4)\), obtaining a multiplicity-one result.
