Query: Quasi-modular forms attached to elliptic curves: Hecke operators   In this article we introduce Hecke operators on the differential algebra of
geometric quasi-modular forms. As an application for each natural number $d$ we
construct a vector field in six dimensions which determines uniquely the
polynomial relations between the Eisenstein series of weight 2,4 and 6 and
their transformation under multiplication of the argument by $d$, and in
particular, it determines uniquely the modular curve of degree $d$ isogenies
between elliptic curves.
