Caenpeel (engineering sciences, Free University of Brussels, Belgium) and van Oystaeyen (mathematics, University of Antwerp, Belgium) present work from a spring 2002 conference spotlighting new results in classical Hopf algebras, classification theory of finite dimensional Hopf algebras, categorical aspects, connections with mathematical physics, and recent developments in the theory of quasi-Hopf algebras. Some specific topics presented include algebra properties invariant under twisting, Cuntz algebras and dynamical quantum group SU, quotients of finite quasi-Hopf algebras, and adjointable monoidal functors and quantum groupoids.
