On the morse index theorem
WebA note on the Morse index theorem for geodesics between submanifolds in semi-Riemannian geometry Piccione, Paolo ; Tausk, Daniel V. The computation of the index of the Hessian of the action functional in semi-Riemannian geometry at geodesics with two variable endpoints is reduced to the case of a fixed final endpoint. WebMorse Inequalities Theorem (Morse Inequalities) Let hbe a Morse function on the compact manifold M. Let j denote the j-th Betti number b j(M) = dimH j dR (M) and let j denote the number of critical points of index j. Then we have the inequality Xk j=1 ( 1)j j Xk j=1 ( 1)j j with equality when k= dimM. A standard proof could be found in Milnor ...

WebSuppose there exists a Morse function on M with exactly two critical points. Then M is homeomorphic to a sphere. This theorem shows that a \choice" of Morse function can give results about the under- lying space that are independent of the choice of Morse function. Eventually we generalise this idea and develop Morse homology. WebThe basic theorem is that the resulting homology is an invariant of the manifold (that is,, independent of the function and metric) and isomorphic to the singular homology of the manifold; this implies that the Morse and singular Betti numbers agree and gives an immediate proof of the Morse inequalities.
Web7 de jul. de 2010 · Nils Waterstraat We give a short proof of the Morse index theorem for geodesics in semi-Riemannian manifolds by using K-theory. This makes the Morse index theorem reminiscent of the Atiyah-Singer index theorem for families of selfadjoint elliptic operators.
