A note on the twisted degree $6$ $L$ -function for Hermitian cusp forms of degree $2$

Rafail Psyroukis

Let $F$ be a cuspidal Hermitian eigenform of degree two over $Q (i)$ , with first Fourier-Jacobi coefficient not identically zero. Building on a paper by Das and Jha, we pro…

Analytic Properties of an Orthogonal Fourier-Jacobi Dirichlet Series

Rafail Psyroukis

We investigate the analytic properties of a Dirichlet series involving the Fourier-Jacobi coefficients of two cusp forms for orthogonal groups of signature $(2, n + 2)$ . Using an orth…

A Fourier-Jacobi Dirichlet series attached to modular forms of $S O (2, 4)$

Thanasis Bouganis, Rafail Psyroukis

We consider a Dirichlet series $D (F, G; s)$ attached to two automorphic forms $F$ and $G$ of an orthogonal group of real signature $(2, 4)$ , involving their Fourier--Jacobi coefficien…

On a Rankin-Selberg integral of three Hermitian cusp forms

Thanasis Bouganis, Rafail Psyroukis

Let $K = Q (i)$ . We study the Petersson inner product of a Hermitian Eisenstein series of Siegel type on the unitary group $U_{5} (K)$ , diagonally-restricted on $U_2(K)\time…

A Fourier-Jacobi Dirichlet series for cusp forms on orthogonal groups

Rafail Psyroukis

We investigate a Dirichlet series involving the Fourier-Jacobi coefficients of two cusp forms $F, G$ for orthogonal groups of signature $(2, n + 2)$ . In the case when $F$ is a Hecke ei…
