Title

Poisson-Lie groups and quasi-Poisson spaces as semi-classical limits of (quasi-) Hopf algebras

Abstract

In this second lecture we show how (quasi-) Hopf symmetries, that were found in the realm of quantum theory, led to interesting new structures in (classical) Poisson geometry.

We consider so-called (quasi-) Poisson-Lie groups as the semi-classical limits of (quasi-) Hopf algebras and, in particular, compare the (quasi-) Lie-bialgebra structures of the Lie algebra su(2).
