| Dec 2, 2022 at 10:14 | comment | added | YCor | I think that the Neeb-Wagemann paper arxiv.org/abs/math/0511260 addresses this question (see notably Section 6 — which is Section 7 in the published version). It is also discussed here where it is observed that the (correct) results of Neeb-Wagemann contradict previous work on the subject by Zusmanovich. I think the semisimple case was due to Kassel-Loday, it has significant simplification because of the vanishing of $H_1$ and $H_2$ of the original Lie algebra and surjectivity of the Koszul map. | |
