Re: Boolean Algebra module

Shouldn't it be better to implement the assumptions system with specialised classes instead of using strings and some make-shift classes ? A sort of abstraction layer, so to speak. Keeping the layer itself small will make it easier to implement it in Cython and should be enough to more than

[PATCH 0/2] Add preliminary solver for separable differential equations case

Hey! I played a bit with sympy and when trying to solve some quasilinear differential equations, but had to first make sure that sympy can handle some simpler forms of PDEs. The patches can be seen from: https://code.plaes.org/git/sympy/log/?h=pde-upstream Cheers, Priit :)
