Query: Derived Hecke algebra for weight one forms   We study the action of the derived Hecke algebra on the space of weight one
forms. By analogy with the topological case, we formulate a conjecture relating
this to a certain Stark unit.
  We verify the truth of the conjecture numerically, for the weight one forms
of level $23$ and $31$, and many derived Hecke operators at primes less than
$200$. Our computation depends in an essential way on Merel's evaluation of the
pairing between the Shimura and cuspidal subgroups of $J_0(q)$.
