Bott periodicity
WebMar 25, 2024 · As a consequence of his proof, the stable homotopy group of classical matrix Lie groups including the unitary group, the orthogonal group, and the sympletic group have periodicity going like: Meanwhile, in K -theory people also call the periodicity of Grothendieck ring as Bott periodicity. Webviewed as a consequence of Bott periodicity in topological K-theory. The main goal of this thesis is to express precisely the manner in which Bott periodicity manifests itself in commutative algebra: it turns out that the answer is Kn orrer periodicity, a behavior of maximal Cohen-Macaulay modules over certain hypersurface rings discovered by

In 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 … See more Bott showed that if $${\displaystyle O(\infty )}$$ is defined as the inductive limit of the orthogonal groups, then its homotopy groups are periodic: and the first 8 … See more One elegant formulation of Bott periodicity makes use of the observation that there are natural embeddings (as closed subgroups) between the classical groups. The loop spaces in Bott periodicity are then homotopy equivalent to the symmetric spaces of … See more The context of Bott periodicity is that the homotopy groups of spheres, which would be expected to play the basic part in algebraic topology by analogy with homology theory, have proved elusive (and the theory is complicated). The subject of See more Bott's original proof (Bott 1959) used Morse theory, which Bott (1956) had used earlier to study the homology of Lie groups.
