Abstract:It is shown that the Koecher-Maass series for positive definite Fourier coefficients of a real analytic Siegel-Eisenstein series of degree 2 has a meromorphic continuation and a simple functional equation.
“…The positive definite case was first proved in [24]. The only special case for degree 2 indefinite Fourier coefficients was treated in [25], which can be proved again from Theorem 4.…”
The author gives the analytic properties of the Rankin–Selberg convolutions of two half-integral weight Maass forms in the plus space. Applications to the Koecher–Maass series associated with nonholomorphic Siegel–Eisenstein series are given.
