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).

Bott periodicity theorem - Wikipedia

This fact is equivalent to the existence of a Thom isomorphism in $ K $- theory for complex vector bundles. In particular, $ P(1 \oplus 1) = X \times S ^ {2} $. Bott's periodicity theorem was first demonstrated by R. Bott [1] using Morse theory, and was then re-formulated in terms of $ K $- theory [6] ; an analogous theorem has also been demonstrated for real fibre bundles.

If E is a vector bundle aver X E m (the dimension cf the fibers may vary, on the components of X) we write IC(E) for the unit disc bundle of E (relative to sorne Riemann structure) and denote its boundary by lO(E). The pair (lD(E), lO(E)) as well as the quotient space lD(E)/13(E) will be denoted by XE.

Complex vector bundle - Wikipedia

The complex version ofKO(X)g, calledK(X)e, is constructed in the same way asKO(X)g but using vector bundles whose fibers are vector spaces over Crather than R. The complex form of Bott Periodicity asserts simply thatK(Sen)is Zforneven and 0 fornodd, so the period is two rather than eight.

To check that the Chern character of any complex vector bundle on is integral, one thus reduces to analyzing the image of as above. This is convenient because the group is very simple. By the Bott periodicity theorem, it is generated by the th power of where is the Hopf bundle over , so that.

Chapter 3 The Hirzebruch-Riemann-Roch Theorem 3.1 Line Bundles, Vector Bundles, Divisors From now on, X will be a complex, irreducible, algebraic variety (not necessarily smooth). We have (I) X with the Zariski topology and O X = germs of algebraic functions. We will write X or X Zar. (II) X with the complex topology and O X = germs of algebraic functions. We will write XC for this.

example, extrinsic vector bundles are used to model subatomic particles. Sections of vector bundles are generalized vector-valued functions. For example, sections of the tangent bundle TM Ñ M are vector fields on the manifold M.

Raoul Bott (September 24, 1923 – December 20, 2005) was a Hungarian-American mathematician known for numerous basic contributions to geometry in its broad sense. He is best known for his Bott periodicity theorem, the Morse–Bott functions which he used in this context, and the Borel–Bott–Weil theorem.
