摘要:对于任意非负整数v,我们显式构造了⌊v/2⌋+1个协变双线性微分算子,从jk, m×Jk ‘, m ’到jk +k ‘ +v, m+m ’。作为一个应用,我们构造了一个协变双线性微分算子mappingS(2)k×S(2)k ' tos (2)k+k ' +v。其中,m表示权重和指标的Jacobi形式的空间;(2)k表示2次和权重的Siegel模形式的空间。所构造的协变双线性微分算子与R. Rankin和H. Cohen在椭圆情况下研究的算子类似,我们称其为Rankin - Cohen算子。
Abstract For any non-negative integer v we construct explicitly ⌊v/2⌋+1 independent covariant bilinear differential operators fromJk, m×Jk′, m′toJk+k′+v, m+m′. As an application we construct a covariant bilinear differential operator mappingS(2)k×S(2)k′toS(2)k+k′+v. HereJk, mdenotes the space of Jacobi forms of weightkand indexmandS(2)kthe space of Siegel modular forms of degree 2 and weightk. The covariant bilinear differential operators constructed are analogous to operators already studied in the elliptic case by R. Rankin and H. Cohen and we call them Rankin–Cohen operators.
