![The basis problem for modular forms on [capital Greek]Gamma₀([italic]N)](https://covers.openlibrary.org/b/isbn/0821824813-M.jpg?default=false)
The "basis problem'' for modular forms (of degree one) is to find a basis for a space of modular forms with elements whose Fourier coefficients can be computed explicitly. The authors give a general treatment for all cases. The main idea in the solution is to consider two kinds …
