WebTopological K-theory is a key tool in topology, differential geometry and index theory, yet this is the first contemporary introduction for graduate students new to the subject. No … WebJan 18, 2024 · I am reading a 2009 paper by Kitaev on K-theory classification of topological insulators. In the 4th page, 1st paragraph in the section "Classification principles", he says, Continuous deformation, or homotopy is part of the equivalence definition, but it is not sufficient for a nice classification.

Indeed, for any k-vector bundle p: E!X, there is a continuous mapping 0 E: X !Egiven by 0 E(x) = 0 Ex, where 0 Ex 2E x is the 0-element of the bre vector space E x.

A (complex) topological vector bundle of rank r, p: E→ T, on a space T is a WebIn mathematics, particularly topology, the K-topology is a topology that one can impose on the set of all real numbers which has some interesting properties. Relative to the set of all … WebIn mathematics, topological K-theory is a branch of algebraic topology. It was founded to study vector bundles on topological spaces, by means of ideas now recognised as (general) K-theory that were introduced by Alexander Grothendieck. The early work on topological K -theory is due to Michael Atiyah and Friedrich Hirzebruch . spelets historia
