A K-Theoretic Proof of the Morse Index Theorem in Semi-Riemannian Geometry
Published 7 Jul 2010 in math.DG and math.SP | (1007.1190v3)
Abstract: 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.
