Abstract
The notion of concrete monoidalW *-category is introduced and investigated. A generalization of the Tannaka-Krein duality theorem is proved. It leads to new examples of compact matrix pseudogroups. Among them we have twistedSU(N) groups denoted byS μ U(N). It is shown that the representation theory forS μ U(N) is similar to that ofSU(N): irreducible representations are labeled by Young diagrams and formulae for dimensions and multiplicity are the same as in the classical case.

Introduction to Quantum Groups

TL;DR: In this paper, the authors give an elementary introduction to the theory of algebraic and topological quantum groups (in the spirit of S. L. Woronowicz) and recall the basic facts from Hopf (*-) algebra theory, theory of compact (matrix) quantum groups and their actions on compact quantum spaces, and provide the most important examples, including the classification of quantum SL(2)-groups, their real forms and quantum spheres.

Free products of compact quantum groups

TL;DR: In this article, the authors construct and study compact quantum groups from free products of C======*-algebras, and discover two mysterious classes of natural compact groups, A====== u¯¯ �(m) and A====== o¯¯ ��(m), which are non-isomorphic to each other for different m's, and are not obtainable by the ordinary quantization method.
