atiyah suggested a set of axioms for topological quantum field theory which was inspired by segal's proposed axioms for conformal field theory (afterday, segal's idea was summarized in ), and witten's idea of the geometric meaning of supersymmetry, . atiyah's axioms are constructed on gluing the boundary with differentiable (topological or continuous) transformation, while segal's are with conformal transformation. these axioms have been relatively useful for mathematical treatments of schwarz-type qfts, although it isn't clear that they capture the whole structure of witten-type qfts. the basic idea is that a tqft is a functor from a certain category of cobordisms to the category of vector spaces.
