Abstract

Let Γ⊂SL2(ℤ) be a subgroup of finite index, and let [Hscr ] denote the Hecke algebra of Γ. The aim of this note is to give some information about the action of [Hscr ] on spaces of modular forms for certain noncongruence subgroups Γ, which can be deduced from the geometric results of [9].
