[sage-support] Sage support for non-standard congruence subgroups

2011-04-20 Thread jtyard
Does anyone know how to use Sage for computations with congruence subgroups other than Gamma, Gamma0, Gamma1 and GammaH? I need the group Gamma(n,2n) = \{gamma in Gamma(n) : 2n | ab, 2n | cd}, as defined in Ihara's theta function book, for odd n. -- To post to this group, send email to sage-supp

I get this message quite often while using the notebook with the "typeset" button checked. For instance, when listing the (numerical) eigenvalues of a big matrix. Is there a known fix for this? I almost feel like I had stopped getting this error, then it cropped back up in 4.3.4, but I could be

[sage-support] Problem constructing extensions of p-adic fields

2010-03-01 Thread jtyard
Hi, I'm having trouble constructing p-adic cyclotomic fields in Sage (v 4.3.3). For instance, if I try to make Q_p(zeta_p) (for, say p = 3), by entering sage: S. = Qp(3)[] sage: K. = Qp(3).extension(x^2 + x + 1) I get the error: NameError: global name 'split' is not defined However, this work

[sage-support] Changing generators of the unit group of a number field

2010-01-21 Thread jtyard
Is there a way to change the generators used in the internal representation of the unit group of a number field? I am currently doing this by hand in an ad-hoc manner and it is very tedious, not to mention prone to mistakes. To be concrete, consider the following: sage: CyclotomicField(5).unit_g

[sage-support] conjugate(x) versus x.conjugate() - inconsistent behavior

2010-01-12 Thread jtyard
Hi, I don't know if this counts as a bug, so sorry if I'm posting this to the wrong list. Say I define a cyclotomic field in Sage as follows: sage: Q3 = CyclotomicField(3) sage: z3 = Q3.0 Then Sage can compute the complex conjugate independent of an embedding into the complexes: sage: z3.conju
