Formality theorem and bialgebra deformations

Quantum Algebra 2015-08-11 v3

Abstract

In this paper we prove formality of the exterior algebra on V+V* endowed with the big bracket considered as a graded Poisson algebra. We also discuss connection of this result to bialgebra deformations of the symmetric algebra of V considered as bialgebra.
