Observables in 2D BF theory
BF theory in two dimensions has been the subject of intensive study
in the last twenty five years. I will readdress it by highlighting
the TQFT interpretation of the spinfoam approach to its
quantisation. I will also introduce the mathematical model that
allows us to treat surfaces with inbuilt topological defects and
how we expect them to relate to operators in the quantum field
theory.
