Gunningham [G] constructed an extended topological quantum field theory
(TQFT) to obtain a closed formula for all spin Hurwitz numbers. In this note,
we use the gluing theorem in [LP2] to re-prove the Gunningham's formula. We
also describe a TQFT formalism naturally induced from the gluing theorem. 查看全文>>
