The API for eigen-decomposition currently has two issues:
- Doesn't seem to handle complex eigenvalues well
- Requires producing a diagonal matrix of eigenvalues, which may be inefficient
I think we …

Hi all, sorry for this provocative title, but I think it is important.
To make a long story short, CAS in general and here sympy, are impressive when it works, but tends to be a nightmare if not, …

With this issue I would like to get the discussion about a PDE/PDAE interface for the DifferentialEquations.jl ecosystem started.
I should also note that I might be quite biased, because I am also…

**Abstract**
A one-dimensional, steady-state packed-bed reactor model with surface chemistry is being developed. The model solves a system of differential algebraic equations (DAEs) using Sundials …

The symbolic ring (`SR`) in Sage currently considers itself to be a field and therefore also an integral domain:
```
sage: SR.is_field()
True
sage: SR.is_integral_domain()
True
```
However, it is c…

This is a suitable GSOC idea.
Currently the ODE module (sympy/solvers/ode.py) which implements the `dsolve` function is messy. The code there would be easier to understand and maintain if each of t…
