摘要: There is a long standing mathematical problem: how to extend the famous 2+1D Reshetikhin-Turaev TQFT’s down to points to get fully-extended TQFT’s. We will explain why thisproblem is related to how to describe/classify mathematically the gapless edges of a 2d topological order. By analyzing the observables on the 1+1D world sheet of a gapless edge of a 2d topological order, we obtain a new categorical structure: enriched monoidal category, which provides solutions to both problems.
