The concept of Hopf algebras was first introduced in the theory of algebraic topology but in recent years has been developed by many mathematicians and applied to other areas of mathematics such as ...

This timely collection of expository papers highlights progress and new directions in Hopf algebras. Arising from the MSRI workshop on Hopf Algebras in October 1999, some papers consider Hopf versions ...

His research interests are in operator algebras, K-theory, and dynamical systems, which are linked through the study of noncommutative topological spaces. He has published over 15 articles in these ...

The mathematics for this in the case of topologically fault tolerant `surface codes’ is closely related on the one hand to quantum groups, Hopf algebras, braided categories[1] and quantum geometry[2] ...

His research focuses on ergodic theory and operator algebras. Before coming to Münster, he worked at Texas A&M University for 15 years. Before that he held one-year postdocs in Rome (2002-2003), Tokyo ...
