Fiber bundle construction theorem information


The Möbius strip can be constructed by a non-trivial gluing of two trivial bundles on open subsets U and V of the circle S1. When glued trivially (with gUV=1) one obtains the trivial bundle, but with the non-trivial gluing of gUV=1 on one overlap and gUV=-1 on the second overlap, one obtains the non-trivial bundle E, the Möbius strip. This can be visualised as a "twisting" of one of the local charts.

In mathematics, the fiber bundle construction theorem is a theorem which constructs a fiber bundle from a given base space, fiber and a suitable set of transition functions. The theorem also gives conditions under which two such bundles are isomorphic. The theorem is important in the associated bundle construction where one starts with a given bundle and surgically replaces the fiber with a new space while keeping all other data the same.
