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.
