May 31, 2020 at 4:53 comment added Praphulla Koushik @DanielLitt I think I understand what is happening here.. I will think about it and ask if I have any specific question..
May 31, 2020 at 2:44 comment added Daniel Litt @PraphullaKoushik — the point is that the Lie algebra is the tangent space at the identity, or equivalently the space of left-invariant vector fields (since such a vector field is determined by its value at the identity). Now think about the algebra this generates...
May 30, 2020 at 14:46 comment added Praphulla Koushik @Meow any book D-modules? Isn't it too broad suggestion? :) Thanks for suggestion of Gatisgory notes... I will see :)
May 30, 2020 at 13:42 comment added Pulcinella @DanielLitt Do the other generators of the centre have a similar differential geometric interpretation?
May 30, 2020 at 13:41 comment added Pulcinella @PraphullaKoushik Try a book/notes on D modules, e.g. 6.9 of Gaitgory's notes on geometric representation theory.
May 30, 2020 at 4:39 comment added Praphulla Koushik Hi, I know definitions of Lie algebra $\mathfrak{g}$ of a Lie group $G$, Universal env. alegra $U(\mathfrak{g})$ of a Lie algebra $\mathfrak{g}$, differential operators on $G$.. Can you suggest some reference to see more details (possibly a proof) of your statement "$U(\mathfrak{g})$ is the algebra of left-invariant differential operators on $G$"..
