Abstract
We will provide a functional integral approach to study topological quantum field theory as the low energy effect of quantum field theory. Reflection positivity of the Hamiltonian is a first principle in this approach. The higher categorical symmetry appears as an emergent symmetry in the limit.
Speaker Intro
I am currently working on Quantum Fourier Analysis, Quantum Information and Subfactor Theory. I am also interested in category theory, harmonic analysis, knot theory, lower dimensional topology, operator algebras, representation theory in mathematics; and quantum field theory and condensed matter in physics.
