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.
