Atiyah singer指标定理

WebIn differential geometry, the Atiyah–Singer index theorem, proved by Michael Atiyah and Isadore Singer (1963), states that for an elliptic differential operator on a compact manifold, the analytical index (related to the dimension of the space of solutions) is equal to the topological index (defined in terms of some topological data). It includes many other … Webgeometric invariants of Dirac operators appear in §7. In §8 we turn to physics, which was Atiyah’s focus after the mid 1980’s and which provided an unanticipated playground for …
