Atiyah-Singer index theorem



Michael Atiyah and Isadore Singer associated two differently defined numbers to an elliptic operator on a manifold: the topological index and the analytical index. The index theorem asserts that the two are equal.

A proof of the Atiyah-Singer index theorem in terms of KK-theory/E-theory has been given by Nigel Higson, an account is in

From the point of view of physics

The index theorem is supposed to have an interpretation in terms of the quantum field theory of the superparticle on the given space.

Traditional physics arguments along these lines include for instance
