Can we apply the theorem of quantization of Lie bialgebras of Etingof-Kazdhan http://www.springerlink.com/content/h285401597138rg7/ to a Poisson manifold $\textbf{R}^{n}?$ Does it give something in comparison to Kontsevitch celebrated formula about star products on $\textbf{R}^{n}$.probably i am missing something very obvious, sorry for that, i am a beginner in this field
