Fredrik, is it possible to compute other Dirichlet series using mpmath? That is, ones that aren't necessarily L-functions, like at http://en.wikipedia.org/wiki/Dirichlet_series? I couldn't find this on that page, but perhaps they're elsewhere.
I realize these usually are some variant on zeta and computable that way, but it is nice to be able to "compare" summation with the "correct" value. - kcrisman On Jun 7, 11:31 am, Fredrik Johansson <[email protected]> wrote: > On Tue, Jun 7, 2011 at 2:33 PM, Pablo De Napoli <[email protected]> wrote: > > > Hi, > > > Though Sage has some extensive support for Riemann zeta function and > > L-series (through. lcal) , it seems to > > have no function for computing some common generalizations of it, like > > Hurwitz zeta function o Lerch trascendent. > > > I've found through the article in wikipedia that in > > >http://aksenov.freeshell.org/lerchphi.html > > > there are some programs for computing Lerch function, but > > unfortunately the code is not GPL-compatible. > > (According to the user guide commercial use is not permited) > > mpmath has both the Hurwitz zeta function and the Lerch transcendent, > for complex arguments and with arbitrary precision.
