Changes (by davidloeffler):
* keywords: => newform dirichlet character
* status: new => needs_review
Old description:
> Newforms of level Gamma1(N), or GammaH(N) (after 8716), are always
> eigenforms for the diamond operators (i.e. they have a character) but we
> don't at present have any way of calculating it.
New description:
Newforms of level Gamma1(N), or GammaH(N) (after #8716), are always
eigenforms for the diamond operators (i.e. they have a nebentypus
Dirichlet character) but we don't at present have any way of calculating
it.
This will be needed for ongoing work on local components of newforms.
