Abstract
Let be a quadratic Poisson bivector on a vector space . Then one can also consider as a quadratic Poisson bivector on the vector space . Fixed a universal deformation quantization (prediction some weights to all Kontsevich graphs [K97]), we have deformation quantization of the both algebras and . These are graded quadratic algebras, and therefore Koszul algebras. We prove that for some universal deformation quantization, independent on , these two algebras are Koszul dual. We characterize some deformation quantizations for which this theorem is true in the framework of the Tamarkin's theory [T1].
