Abstract

We study quantum deformations of Poisson orbivarieties. Given a Poisson manifold (Rm,α)(\mathbb{R}^{m},\alpha) we consider the Poisson orbivariety (Rm)n/Sn(\mathbb{R}^{m})^{n}/S_{n}. The Kontsevich star product on functions on (Rm)n(\mathbb{R}^{m})^{n} induces a star product on functions on (Rm)n/Sn(\mathbb{R}^{m})^{n}/S_{n}. We provide explicit formulae for the case h×h/W{{\mathfrak h} \times {\mathfrak h}}/\mathcal{W}, where h{\mathfrak h} is the Cartan subalgebra of a classical Lie algebra g{\mathfrak g} and W\mathcal{W} is the Weyl group of h{\mathfrak h}. We approach our problem from a fairly general point of view, introducing Polya functors for categories over non-symmetric Hopf operads.
