As part of my research on the new assumption system, I encountered some
problems with the logic module (sympy.core.facts),
and I implemented some things quickly (and possibly wrong) because I needed
them, but my knowledge of Artificial Intelligence and
First-order-logic is practically nonexistent.

currently SymPy has a rather confusing behaviour:
In [1]: isprime(1)
Out[1]: False
In [2]: Integer(1).is_prime
Out[2]: True
I'd be glad to fix this, but ... which one is correct?

Hi all. As part of my work in the assumptions branch[1], I'm faced to the
problem of finding a new syntax for the expr.is_* property.
It seems that last time we talked about it, we used the following syntax for
querying an element (although we did not discuss it)
IsPositive(x)
IsElement(x)
etc.

In this email, I'll expose some design ideas for the new assumptions system.
It would be great if I get some feedback and we agree on a clear design that
we can implement.
-
The basic idea is to decouple the assumptions from the model, so that new
assumptions can be created without having

Hi!
Could someone please explain the syntax for rsolve_ratio ?
I'ver read the docstrings, but they are not very helpful for someone that
does not know much about recurrence relations. I can clearly understand
mathematica's RSolve:

There's an issue with the makefile in the docs, that the rst2html converter
is called rst2html on Debian systems, but rst2html.py on (nearly all) other
systems ...
Does anyone know a way to specify in the Makefile: use rst2html and if this
is not available, try rst2html.py (without going to autoto

To my mind comes for example the method Basic.as_poly, which I think
is superfluous since it is in Basic, but there are no uses for this in
methods in the core
(why not use Poly() instead?)

Hi!
Could it be possible to access git through http?
You see, In my campus, the port for git:// is blocked so having an http
mirror would be
much apreciated ...
Thanks,
