Query: The Weil representation and Hecke operators for vector valued modular
  forms   We define Hecke operators on vector valued modular forms transforming with
the Weil representation associated to a discriminant form. We describe the
properties of the corresponding algebra of Hecke operators and study the action
on modular forms.
