Topological k-theory
WebThere are two (or three maybe) way to go to the topological K-theory, one is from the algebraic topology (or vector bundles), the other is from (download) the operator K-theory (the K-theory of C*-algebras). Form the algebraic topology: there are many second course book mention it, for example: May J P. A concise course in algebraic topology [M ... WebJust like the fundamental group and the de Rham cohomology groups, K-theory provides topological invariants of smooth manifolds. These topological invariants are constructed from isomorphism classes of vector bundles over manifolds. Among the early applications of K-theory to topology was a simple proof that the only spheres which possess ...
