WebThe Atiyah-Singer index theorem is a remarkable result that allows one to compute the space of solutions of a linear elliptic partial differential operator on a manifold in terms of purely topological data related to the manifold and the symbol of the operator. First proved by Atiyah and Singer in 1963, it marked the
Web2. The Atiyah-Singer Index Theorem In this section I give a quick survey of index theory results. You can skip this section if you want. Given Banach spaces S and T, a bounded linear operator L : S →T is called Fredholm if its range is closed and its kernel and cokernel T˚L(S) are finite dimensional. The index of such an operator is ... Web$\begingroup$ It is true that just about any equation in physics is a differential equation! Not all lead to index problems, though. (I did mean S^4. Instantons are time-dependent field configurations.) An example from string theory, whose Feynman diagrams are two-dimensional QFT amplitudes.
