Topological quantum field theories are linear representations of (extended) cobordism. On the one hand they are a powerful source of algebraic invariants of manifolds (classical examples are the Jones polynomial, Turaev-Viro, and Dijkgraaf-Witten invariants). On the other hand, the intuition coming from the geometric nature of cobordism provides a clear explanation for otherwise mysterious algebraic constructions. An intriguing example is provided by elliptic cohomology. This is known in the physics folklore to be related to a certain supersymmetric quantum field theory, yet a rigorous construction remains elusive and an appealing challenge to mathematicians.
