我们构造了从 r 次的椭圆模尖点形式 f 和 r 次厄密模尖点形式 g 到 n+ r 次厄密模尖点形式的提升。该电梯就是所谓的宫胁电梯。当f和g是“赫克本征型”时,它的升力也是“赫克本征型”(如果它不全为零)。此外,我们明确确定了与宫胁电梯相关的标准 L 函数和 A 参数。
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. This lift is the so-called Miyawaki lift. 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.
