A certain Dirichlet series of Rankin-Selberg type associated with the Ikeda lift of half-integral weight

In this article we obtain an explicit formula for certain Rankin-Selberg type Dirichlet series associated to certain Siegel cusp forms of half-integral weight. Here these Siegel cusp forms of half-integral weight are obtained from the composition of the Ikeda lift and the Eichler-Zagier-Ibukiyama correspondence. The integral weight version of the main theorem had been obtained by Katsurada and Kawamura. The result of the integral weight case is a product of $L$-function and Riemann zeta functions, while half-integral weight case is a infinite summation over negative fundamental discriminants w…

Hermitian Maass lift for General Level

For an imaginary quadratic field $K$ of discriminant $-D$, let $χ= χ_K$ be the associated quadratic character. We will show that the space of special hermitian Jacobi forms of level $N$ is isomorphic to the space of plus forms of level $DN$ and nebentypus $χ$ (the hermitian analogue of Kohnen's plus space) for any integer $N$ prime to $D$. This generalizes the results of Krieg from $N = 1$ to arbitrary level. Combining this isomorphism with the recent work of Berger and Klosin and a modification of Ikeda's construction we prove the existence of a lift from the space of elliptic modular forms t…

Rankin-Selberg method for Jacobi forms of integral weight and of half-integral weight on symplectic groups

In this article we show analytic properties of certain Rankin-Selberg type Dirichlet series for holomorphic Jacobi cusp forms of integral weight and of half-integral weight. The numerators of these Dirichlet series are the inner products of Fourier-Jacobi coefficients of two Jacobi cusp forms. The denominators and the range of summation of these Dirichlet series are like the ones of the Koecher-Maass series. The meromorphic continuations and functional equations of these Dirichlet series are obtained. Moreover, an identity between the Petersson norms of Jacobi forms with respect to linear isom…

半整权弱全纯模形式的$p$ -adic极限

$p$-adic Limit of Weakly Holomorphic Modular Forms of Half Integral Weight

Serre得到了$p=2,3,5,7$在$SL_2(\mathbb{Z})$上的模形式的积分傅里叶系数的p-adic极限.本文将Serre的结果推广到$Γ_{0}(4N)$上的半整权弱全纯模形式，并推广到$N=1,2,4$上。利用半整权的模形式的傅里叶系数之间的线性关系给出了一个证明。作为应用，我们得到了Borcherds指数的同余，Eisentein级数的商的同余以及$L$ -函数在某一点的值的同余.利用Ikeda提升，得到了Maass空间上Siegel模形式的傅里叶系数的同余关系.
