L-infinity Formality check for the Hochschild Complex of Certain Universal Enveloping Algebras
Martin Bordemann, Olivier Elchinger, Simone Gutt +1
We study the L-infinity-formality problem for the Hochschild complex of the universal enveloping algebra of some examples of Lie algebras such as Cartan-3-regular quadratic Lie alg…

A formality framework for commutative deformations
Olivier Elchinger
In this article, we use Harrison cohomology to provide a framework for commutative deformations. In particular, Kontsevich's result that formality of (the Hochschild complex of) an…
