[sage-support] Contour-plot of Weierstrass-p-Function

2008-05-19 Thread Kai
Hi there, i'm having yet another problem with plotting the Weierstrass-p- Function. This time i'd like do create a contour plot of it. I did the following: sage: i=CDF.0 sage: tau=i sage: Om=pari([1,tau]) sage: def f(a,b): return abs(Om.ellwp(a+b*i)) sage: T=contour_plot(f, (0.1,0.9), (0.1,0.9),

Hi, Yes, I know that for lots of negative real numbers x^x is not defined, but for some values of x, such as x=-1 or x=-1/3 there is a real number answer and I don't see anything plotted. Why isn't anythng plotted at those discrete set of values? Dan On May 16, 5:37 pm, Robert Bradshaw <[EMAIL

[sage-support] Sage Question: Computing torsion subgroups of ECs over arbitrary number fields

2008-05-19 Thread Dan Shumow
Presently, in sage, is there anyway to computer the torsion subgroup of a curve over an arbitrary number field? I'm pouring through the documentation, and I see how to do it for a curve over the rationals. Is this not implemented for number fields? Thanks, Dan --~--~-~--~~-
