Webcomputational-friendly. Hence, the strategy for using Clifford algebras to prove Bott periodicity is to find alternative models for topological K-theory which are closely related to Clifford algebras, so we can use Clifford algebras to prove the Bott periodicity in those models first; then show that the Bott periodicity in the WebOne manifestation of Bott periodicity is that [ Cliff 1] has order 8. We will soon see a very easy proof of this fact. A theorem of C. T. C. Wall is that [ Cliff 1] in fact generates the super Brauer group; I believe this can be shown by classifying super division algebras, as discussed below. Bott periodicity

WebOct 14, 2016 · Every module of the Clifford algebra Cl_k defines a particular vector bundle over §^ {k+1}, a generalized Hopf bundle, and the theorem asserts that this correspondence between Cl_k -modules and stable vector bundles over §^ {k+1} is an isomorphism modulo Cl_ {k+1} -modules. WebIn mathematics, the Bott periodicity theorem describes a periodicity in the homotopy groups of classical groups, discovered by Raoul Bott ( 1957, 1959 ), 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.
