[sage-devel] No module named floor

2011-06-17 Thread Kiran Kedlaya
I succeeded in building 4.7 on my legendarily wonky 64-bit Fedora box (which lives on a 32-bit network and thus is a source of many bug reports). But as soon as I try to run doctests, I get the following error on pretty much every file: {{{ sage -t "devel/sage/sage/symbolic/constants.py" Traceback

[sage-devel] Where should Fourier sum stop?

2011-06-17 Thread Andrey Novoseltsev
Hello, There is a discrepancy between the documentation and behaviour of partial sums of Fourier series: http://trac.sagemath.org/sage_trac/ticket/8603 If the cut-off parameter is N, then the documentation says that N-th term will be included, but it is not. To fix it, one should either adjust t

[sage-devel] Re: Abelian group invariants

2011-06-17 Thread Dan Gordon
Hi Rob and Javier, Sorry I wasn't clear in my posting. I agree that the way things are done now isn't correct, and what I'm suggesting is to have elementary_divisors return the list of prime powers, and invariant_factors return the m_i's. Rob's suggestion of doing this within the finitely-genera

[sage-devel] Abelian group invariants

2011-06-17 Thread Dan Gordon
Back in 2008 there was a discussion of the elementary_divisors function for abelian groups. While it's not universal, most group theory and algebra books define the elementary divisors of a finite abelian group G to be a list of prime powers such that G is isomorphic to the direct product of cycli
