在下面的文章中,我们考虑关于模的同余子群 \( \Gamma _0 (N) = \{ (\begin{array}{*{20}c} a & b \\ c & d \\ \end{array} ) \in \Gamma :c \equiv 0\bmod N\} \) 的全纯模形式 组 γ。当然,全纯条件包括尖点。我们用 Sk(Γ0(N),χ) 表示权重 k 和字符 χ 的这些形式的空间,即满足 $$ f(\frac{{az + b}} {{cz + d}})(cz + d)^{ - k} = \chi (a)f(z) $$ 对于 Γ0(N) 的所有替换,其在尖点处消失。
In the following article we consider holomorphic modular forms with respect to the congruence subgroup \( \Gamma _0 (N) = \{ (\begin{array}{*{20}c} a & b \\ c & d \\ \end{array} ) \in \Gamma :c \equiv 0\bmod N\} \) of the modular group Γ. Of course the holomorphy condition includes the cusps. By Sk(Γ0(N),χ) we denote the space of these forms of weight k and character χ, i.e. those satisfying $$ f(\frac{{az + b}} {{cz + d}})(cz + d)^{ - k} = \chi (a)f(z) $$ for all substitutions of Γ0(N), which vanish in the cusps.
