Asymptotic Fredholm Modules, Vector Bundles with Small Variation and a Nonvanishing Theorem for K-Theoretic Indices Academic Article uri icon


  • We introduce the concept of asymptotic Fredholm module to prove a nonvanishing theorem for K-theoretic indices of elliptic operators. The nonvanishing theorem is applied to study positive scalar curvature and spectrum of the Laplacian on noncompact manifolds. 1998 Kluwer Academic Publishers.
