Hauptseminar Modulformen

It is an important problem to construct interesting automorphic forms on groups of higher degree. Ikeda constructed the Miyawaki lift which is a lifting of Siegel cusp forms given by pulling back of the Ikeda lift. In this lecture, we consider the Miyawaki lifts of hermitian modular forms. We construct a lifting from an elliptic modular cusp form f and a hermitian modular cusp form g of degree r to a hermitian modular cusp form of degree n+r. When f and g are Hecke eigenforms, its lift is also a Hecke eigenform (if it is not identically zero). Moreover, we determine explicitly the standard L-function and the A-parameter associated to the Miyawaki lift. This is a joint work with H. Atobe.
