== Generalized Bernoulli Numbers == PEOPLE: William Stein * There is a simple 2 or 3 line formula for generalized Bernoulli numbers in terms of non-generalized ones, which could be used to speed up the chi.bernoulli_number(k) command (for a Dirichlet character chi) by a factor of thousands. * [[/bern||more details]] |
