QUASIMODULAR FORMS AND COHOMOLOGY
Abstract We construct linear maps from the spaces of quasimodular forms for a discrete subgroup Γ of SL (2,ℝ) to some cohomology spaces of the group Γ and prove that these maps are equivariant with respect to appropriate Hecke operator actions. The results are obtained by using the fact that …
