Some remarks on Rankin-Cohen brackets of eigenforms
arXiv:1111.2431 · doi:10.1142/S1793042112501175
Abstract
We investigate the cases for which products of two quasimodular or nearly holomorphic eigenforms are eigenforms. We also genaralize the results of Ghate \cite{ghate1} to the case of Rankin-Cohen brackets.
