Operator algebras, quantum field theory, and topological physics
Abstract: A group gives a classical notion of symmetry. We have seen a new type of "quantum symmetries" in many different fields in mathematics and physics over the last four decades. I will present recent advances in this area based on theory of von Neumann algebras in connection to chiral conformal field theory and two-dimensional topological physics. This is a general talk without much technicality.
