Abstract: A topological field theory in d dimensions associates to each
(d-1)-dimensional closed manifold M an inner-product space V(M), and to
each d-dimensional manifold W with boundary M a vector v(W) in V(M),
satisfying certain natural axioms; for example, V(-) takes disjoint
unions
to tensor products, and behaves well under diffeomorphisms. There are
many
flavours of topological field theories - one may for example assume that
all of the manifolds are oriented, or spin, or carry a free action of a
finite group G.
