I'm an adjoint researcher at IMPA (Rio de Janeiro). My interests are in vertex algebras, CFT, sigma-models and their relations to geometry.

Should Bott really be a part of it? I mean computing $H^0$ :)

comment classification for coadjoint orbits of lower or upper triangular matrices
@PDC: I think the question refers to coadjoint orbits for the unipotent group. So you're not allowed to conjugate by elements of GL_n. The complete characterization is in the reference pointed above in the comments.

"unknown"=Cavazzani or Moci? and if so the series is arXiv:1303.0902?

@Ricardo: Thanks! I sporadically come back to MO and forget those quirks.

comment Degree of a commutator in a hyperalgebra or enveloping algebra
The associated graded is a Poisson algebra and the Poisson bracket is graded there. If $\sigma(X)$ denotes the symbol of $X$, then I suppose your question is when ${\sigma(X), \sigma(Y)}\neq 0$. I'm not sure there's more you can say.
