[sage-support] var() function behavior changes when calculus.py is imported

When "from sage.calculus.calculus import *" is executed, the default var() function from sage.calculus.var (L4) gets replaced by another one from sage.symbolic.ring (L506). There is indeed an import made in sage.calculus.calculus (L370). However, the behavior of var() changes afterward because wh

[sage-support] Re: Issues with simplifying really simple expressions

I guess the problem is that currently Pynac do not process powers with symbolic exponents much. (x**a)**b, (x**b)**a and x**(a*b) won't match, but I guess that none of them is canonical. The only way to process (some of) them is through simplify() (and so through Maxima): sage: ((x^a)*(x^b)).simpli

You were right, there is something wrong with the libgfortran file under SAGE_ROOT/local/lib/ . It was a symlink to "./../lib/libgfortran.so", strange. Sage is working with the libraries you posted above. Thanks ! -- To post to this group, send email to sage-support@googlegroups.com To unsubscri

I can confirm it fixes the bug, I'll add myself as a reviewer on Trac. If I understand correctly, originally, __copy__ function of element.pyx calls Expression.__new__(Expression) which should call an __init__ function (without argument ? but I don't know which ?) so _gobj is not initialized. When
