People,
my colleage searches for a free CA library which operates with
Lie algebras.
Has FriCAS such?
1. Let a Lie algebra be given by several generators
(say, a, b, c, d, e), and several relations between them
(like this: [b, [a, c]] - 2*[c, [d, [b, e]]] = 0).
And one needs to build a matrix representation for this algebra,
and to compute things in it.
2. It is also desirable to build a polynomial vector fields that
represent this algebra.
Has FriCAS something for this?
Thanks,
------
Sergei
