Bruinier和Ono最近发展了广义Borcherds乘积理论,它使用某些Maass形式的系数作为亚纯模形式的无限乘积展开式的指数。利用这一点,人们可以使用经典的结果同余的模形式,以获得同余的马斯形式。本文给出了Ramanujan模拟θ函数f和ω的例子。
Bruinier and Ono recently developed the theory of generalized Borcherds products, which uses coefficients of certain Maass forms as exponents in infinite product expansions of meromorphic modular forms. Using this, one can use classical results on congruences of modular forms to obtain congruences for Maass forms. In this note we work out the example of Ramanujan’s mock theta functionsfandωin detail.
