Combinatorial 2d higher topological quantum field theory from a local cyclic algebra
Justin Beck, Andrey Losev, Pavel Mnev
We construct combinatorial analogs of 2d higher topological quantum field theories. We consider triangulations as vertices of a certain CW complex . In the "flip theory," cells…
