%0 Journal Article %T A review on deformation quantization of coadjoint orbits of semisimple Lie groups %A R. Fioresi %A M. A. Lledo %J Mathematics %D 2001 %I arXiv %X In this paper we make a review of the results obtained in previous works by the authors on deformation quantization of coadjoint orbits of semisimple Lie groups. We motivate the problem with a new point of view of the well known Moyal-Weyl deformation quantization. We consider only semisimple orbits. Algebraic and differential deformations are compared. %U http://arxiv.org/abs/math/0111132v1
