On The Periodicity Theorem For Complex Vector Bundles

on the periodicity theorem for complex vector bundles

ON THE PERIODICITY THEOREM FOR COMPLEX VECTOR BUNDLES 233 This notation is justified by the fact that the (isomorphism classes of) line-bundles over X then form a multiplicative group with L-l as the inverse of L. The unit of this group is the trivial line-bundle X x 0 (denoted by 1).

In mathematics, the Bott periodicity theorem describes a periodicity in the homotopy groups of classical groups, discovered by Raoul Bott, which proved to be of foundational significance for much further research, in particular in K-theory of stable complex vector bundles, as well as the stable homotopy groups of spheres. Bott periodicity can be formulated in numerous ways, with the periodicity in question always appearing as a period-2 phenomenon, with respect to dimension, for the theory assoc

(PDF) Bott Periodicity, Submanifolds, and Vector Bundles

Topological K–theory, the first generalized cohomology theory to be studied thoroughly, was introduced around 1960 by Atiyah and Hirzebruch, based on the Periodicity Theorem of Bott proved just a few years earlier. In some respects K–theory is more elementary than classical homology and cohomology, and it is also more powerful for certain purposes. Some of the best-known applications of ...

The proof of this theorem is based on three non-trivial theorems, one of which is Bott periodicity.

Let's begin with the case .
