From finite state automata to tangle cobordisms: a TQFT journey from one to four dimensions (2309.00708v2)
Published 1 Sep 2023 in math.QA, cs.FL, math-ph, math.CT, math.MP, and math.RT
Abstract: This is a brief introduction to link homology theories that categorify Reshetikhin--Turaev $\mathsf{SL}(N)$-quantum link invariants. A recently discovered surprising connection between finite state automata and Boolean TQFTs in dimension one is explained as a warm-up.
