Seminar on quantum groups and C*-algebras Monday, 16 October 2023, 11:30 am ================================ Venue: Ramanujan hall Host: Saikat Mazumdar Speaker: Dr. Sutanu Roy Affiliation: NISER Bhubaneswar Title: Braided quantum groups and quantum symmetries in the C*-algebraic framework Abstract: Compact quantum groups naturally generalize compact groups in the realm of noncommutative geometry. They also appear as symmetries of various (classical and quantum) spaces. However, while investigating the semidirect product of compact quantum groups, a more general concept, namely braided compact quantum groups, emerges quite naturally. In this talk, I will provide motivation for braided compact quantum groups and illustrate them with examples. Following that, I will present recent developments in the relationship between braided compact quantum groups and quantum symmetries of spaces (of certain types). If time permits, I shall mention certain aspects of the general theory of locally compact braided quantum groups within the C*-algebraic framework.
