Kontsevich star-product on the dual of a Lie algebra
arXiv:math/9905080
Abstract
We show that on the dual of a Lie algebra $\g$ of dimension , the star-product recently introduced by M. Kontsevich is equivalent to the Gutt star-product on $\g^\ast$. We give an explicit expression for the operator realizing the equivalence between these star-products.
