Something is wrong with the multi-modular matrix multiplication code for matrices over ZZ. At random, and infrequently, it gives incorrect results. For example, the following code chooses random 3…

Yangians can be seen as a deformation of U(**gl**[t]) and have many interesting connections to representation theory. See http://en.wikipedia.org/wiki/Yangian.

Set up the algebra to handle multiple bases; implemented the Kazhdan--Lusztig basis.
This is a follow up to ticket #7729.
See http://wiki.sagemath.org/HeckeAlgebras for some design discussion.

Cubic Hecke Algebras are factors of the group algebra of the Artin braid groups, such that the images `s_i` of the braid generators satisfy a cubic equation:
```
s_i^3 = u s_i^2 - v s_i + w
```…

I am trying to implement something similar to that of https://arxiv.org/pdf/1902.10525.pdf, where they fit the coefficients of cubic polynomials of x, y, and t by minimizing the summed cost function o…

I couldn't believe my eyes when I saw we don't have the Pfaffian implemented in Sage.
Attached is an implementation that computes it over any ring in the combinatorial way using perfect matchings. …
