Bott Generator

Definition

A Bott generator is a specific construction in K-theory, which helps classify vector bundles over spheres by providing a way to represent the stable homotopy classes of vector bundles. It is used to show that the K-theory of spheres can be understood in terms of these generators, simplifying the analysis of vector bundles and their classifications. This concept is pivotal in relating different vector bundles and understanding their structure through algebraic topology.
