Simple compact quantum groups


ABSTRACT: In the mid-80's, Woronowicz introduced the general notion of compact quantum groups. He and Soibelman-Vaksman independently constructed the first non-trivial examples of such objects by the method of deformation of simple compact Lie groups, which are also called the compact real forms of the Drinfeld-Jimbo quantum groups. Later, starting with his Ph.D. thesis, the speaker and his collaborators discovered and studied several new classes of compact quantum groups of a completely different nature. Meanwhile, it has been an outstanding problem to find an appropriate notion of simple compact quantum groups. In this talk, we will propose a definition of simple compact quantum groups and show that the examples mentioned above are simple compact quantum groups. We will also discuss the problem of classifying simple compact quantum groups.
