Generating spaces of modular forms with -quotients
arXiv:math/0701478
Abstract
In this note we consider a question of Ono, concerning which spaces of classical modular forms can be generated by sums of -quotients. We give some new examples of spaces of modular forms which can be generated as sums of -quotients, and show that we can write all modular forms of level as rational functions of -products.
