In iTHEMS Math Seminar on June 7, 2023, Kan Kitamura gave us a talk on his recent research on quantum groups. In the first half of the talk, he introduced the definition of C*-algebras and compact quantum groups. In the latter half of the talk, he explained his theorem on the classification of the discrete quantum subgroups of the quantum double of q-deformed simple Lie groups. The talk was highly clear and stimulating.
