Revision 6082:227c86615158, 382 bytes checked in by William Stein <wstein@…>, 6 years ago (diff)

Improved coverage of testing of modular forms -- ambient_eps, and fixed a few bugs and inefficiencies:

  • bug in _dim_new_eisenstein
  • DirichletGroup?(389,CyclotomicField?(4)) was way way too slow -- made faster by optimizing the function k.zeta(n) for k a cyclotomic field.

4Modular forms with character over a finite field just breaks:

7   Modular Forms space of dimension 2, character [1, -1] and weight 2 over Finite Field of size 7
