Duflo--Kontsevich-type isomorphisms for Tamarkin--Tsygan calculi of dg manifolds

Hsuan-Yi Liao, Mathieu Stiénon, Ping Xu

We establish a Duflo--Kontsevich-type theorem for differential graded (dg) manifolds. Specifically, we prove that the Hochschild--Kostant--Rosenberg maps twisted by the square root…

-Algebras from Lie Pairs

Mathieu Stiénon, Luca Vitagliano, Ping Xu

Given an inclusion of Lie algebroids sharing the same base manifold , i.e. a Lie pair, we prove that the space $Γ(Λ^\bullet A^\vee)\otimes_{R} \frac{U(L)}…
