SpletThe definition of a one-dimensional TQFT. Definition TQFT of dimension 1 is a symmetric, monoidal functor Z : Cob(1) −→C−vect. In particular, it preserves tensor products ⊗. The ⊗in Cob(1) is given by disjoint union of manifolds while ⊗in C−vect is given by the tensor product of vector spaces: Z(M ⊔N) ≃Z(M) ⊗Z(N), Z(∅) ≃C, Splet4.TQFT’s from path integrals Schwarz-type TQFT’s are obtained via path integrals, i.e., integrals over an (infinite-dimensional) space of paths or connections. It is hard to make math-ematical sense of such integrals, but they are fundamental in QFT. The typical example of a Schwarz-type TQFT is Chern-Simons theory, in dimension 2+1. To klown film

SpletC-valued topological quantum field theory (TQFT for short) with tangential structure ξand background fieldsX is a symmetric monoidal functor Z : Bordξ d,d−1 (X) →C. A typical target is C= Vect, the category of vector spaces (over some fixed fieldK). Yet there are plenty of interesting targets other than Vect.
