On a Rankin–Selberg integral of three Hermitian cusp forms

Abstract Let $$K = \mathbb {Q}(i)$$ K = Q ( i ) . We study the Petersson inner product of a Hermitian Eisenstein series of Siegel type on the unitary group $$U_{5}(K)$$ U 5 ( K ) , diagonally-restricted on $$U_2(K)\times U_2(K)\times U_1(K)$$ U 2 ( K ) × U 2 ( K ) × U 1 ( K ) , a...
