Universal central extensions of twisted forms of split simple Lie algebras over rings
Jie Sun
We give sufficient conditions for the descent construction to be the universal central extension of a twisted form of a split simple Lie algebra over a ring. In particular, the uni…

Descent constructions for central extensions of infinite dimensional Lie algebras
Arturo Pianzola, Daniel Prelat, Jie Sun
We use Galois descent to construct central extensions of twisted forms of split simple Lie algebras over rings. These types of algebras arise naturally in the construction of Exten…
