Ikeda constructed a lifting that solves the Duke-Imamoglu conjecture for the case of a rational field, and Yamana extended it to the case of a totally real field. On the other hand, Katsurada gave an explicit formula for the relation between the period of the Ikeda lift and the L-function of the original modular form. In this talk, the speaker extends Katsurada's result to the case of the Ikeda-Yamana Lift.
