We define one-parameter “massive” deformations of Maass forms and Jacobi forms. This is inspired by descriptions of plane gravitational waves in string theory. Examples include massive Green’s functions (that we write in terms of Kronecker–Eisenstein series) and massive modular graph functions.

马斯形式和雅可比形式的大规模变形

我们定义了 Maass 形式和 Jacobi 形式的单参数“大规模”变形。这是受到弦理论中平面引力波描述的启发。示例包括大量格林函数（我们根据 Kronecker-Eisenstein 系列编写）和大量模图函数。
