โฆ Synopsis
We prove the algebraicity of the ratio of the Petersson norm of a holomorphic Hilbert modular form over a totally real number field and the norm of its Saito-Kurokawa lift. We prove a similar result for the Ikeda lift of an elliptic modular form. In order to obtain these we combine some results on local symplectic groups to generalize a special value of the standard L-function attached to a Siegel-Hilbert cuspform.

In a previous paper the second author proved that the image of the Galois representation modulo attached to a Hilbert modular newform is "large" for all but finitely many primes , if the newform is not a theta series. In this brief note, we give an explicit bound for this exceptional finite set of p
