On the coefficients of certain modular forms belonging to subgroups of the modular group
1. Introducton. The Fourier coefficients of modular forms F(r) of positive dimension have been determinedt for the case in which F(Q) belongs to the full modular group. It is the purpose of this paper to generalize some of those results to the case where F(r) belongs to an arbitrary subgroup …
