Boundaries And 3-Dimensional Topological Field Theories

Abstract/Media

Just as differential equations often boundary conditions of various types, so too do quantum field theories often admit boundary theories.  I will explain these notions and then discuss a theorem proved with Constantin Teleman, essentially characterizing certain 3-dimensional topological field theories which admit nonzero boundary theories.  One application is to gapped systems in condensed matter physics.
