A star-product approach to noncompact quantum groups

  • Frédéric Bidegain
  • Georges Pinczon


Using the duality and the topological theory of well-behaved Hopf algebras, we construct star-product models of noncompact quantum groups from Drinfeld and Reshetikhin standard deformations of enveloping Hopf algebras of simple Lie algebras. Our star-products act not only on coefficient functions of finite-dimensional representations, but actually on allC functions, and they even exist for nonlinear (semi-simple) Lie groups.
