A little while back I tried to give a rough idea of what Lie algebras were about. What I want to do now is show how with a bit of Haskell code we can directly get our hands on one. I'm going to assume you know how to make matrices ...
I’ve been looking at Lie algebras/groups for CDS202 tonight: I have to compute the coadjoint action of SO(3) on the dual of its Lie algebra, and find the coadjoint orbits. Exactly what all of that means, and why I care, has ye...
