Abstract
In this talk, we will discuss a geometric version of the Poincaré–Birkhoff–Witt isomorphism for Lie algebras. This version is attached to a closed embedding with split conormal sequence satisfying an additional second-order condition, called tameness. This condition, discovered independently by Shilin Yu, allows us to extend and generalize the work of Kapranov and Markarian in the case of the diagonal embedding. This is joint work with Damien Calaque.
