Web1. Introduction These notes are the outcome of a mini course held at the edition of Winter Braids in Pau in February 2015. The goal of the course was to give an introduction to the notion of TQFT and a taste of how the famous SU(2)-Reshetikhin-Turaev TQFTs can be constructed using skein In gauge theory and mathematical physics, a topological quantum field theory (or topological field theory or TQFT) is a quantum field theory which computes topological invariants. Although TQFTs were invented by physicists, they are also of mathematical interest, being related to, among other things, knot theory and the theory of four-manifolds in algebraic topology, and to the theory of moduli spaces in algebraic geometry. Donaldson, Jones, Witten, and Kontsevich have all …

WebJan 1, 2002 · The notion of extended TQFT’s that we will introduce here and on which our constructions will be based involves higher category theory, namely double categories and double functors. It thus contains both Atiyah’s notion of a TQFT in dimension three and Segal’s notion of CFT as special cases, though they appear on different categorical levels. WebJun 6, 2024 · The resulting theory is not substantially different. In fact, the value of a nonoriented 1-dimensional TQFT valued in finite-dimensional real vector spaces is automatically equipped with a canonical metric, which provides you with a way to introduce metrics using the structure of a TQFT. $\endgroup$ – in the alps folk music is labeled as
