I'm confused by this behavior:
```python
>>> from sympy import *
>>> f = MatrixSymbol(Symbol('f'), Integer(2), Integer(2))
>>> x = Mul(Integer(-1), Determinant(f))
>>> x.is_commutative
False

Requires (these are sketchy thoughts...) :
- From a (system of) polynomial(s), obtain its unfolding (=again a (system of) polys with additional variables).
- Define how to solve linear non-commutative…

It is important that (add x y z) can match to (add a b) with for example
associative
```
{a: (add, x, y), b: z}
```
commutative
```
{a: z, b: (add, y, x)}
```
This can be costly but is quite doa…

From what I understand MathJax's implements AMScd which does not support more advanced (but essential) features like diagonal arrows, which are really needed for making diragrams usable. TiKZcd is my …

Quasi-commutative accumulators have the following property:
```text
h(h(acc, x), y) = h(h(acc, y), x)
```
where `acc` is the accumulated value. In general, these can be used to build zero-know…
