K-star products on dual of Lie algebrasNabiha Ben AmarNabiha Ben AmarDépartement de Mathématiques, Faculté des Sciences de Sfax, Route de Soukra, BP 802, 3018 SFAX, Tunisie, e-mail: Nabiha.BenAmar@fss.rnu.tn Abstract: We consider a generalization $(\star_\alpha)$ of the Kontsevich family of star products $(\star_\alpha^K)$ for linear Poisson structures $\alpha$. Such a family is characterized by a formal function $F$. We study some general properties of such families: invariance and covariance, closeness and relativity, symmetry and reality. Finally, we characterize the Kontsevich family $(\star_\alpha^K)$ among all them. Full text of the article:
