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.
