Dear Sam,
One possibility you might like to try is to "work solely over QQ" by
doing the following. Rather than working with eigenvalues a
I want to consider eigenspaces of S1 =
CuspForms(Gamma0(N),k).new_subspace(), but only for repeated
eigenvalues. So, given a Hecke eigenform T, and a repeated eigenvalue e,
I'd like to take the kernel of T-e acting on S1. This doesn't work because
elements of S1 must have rational coefficients,
