Fiber Bundle

A fiber bundle (also called simply a Bundle) with Fiber is a Map where is calledthe Total Space of the fiber bundle and the Base Space of the fiber bundle. The main condition forthe Map to be a fiber bundle is that every point in the Base Space has a Neighborhood such that is Homeomorphic to in a special way. Namely, if


is the Homeomorphism, then


where the Map means projection onto the component. The homeomorphisms which ``commute withprojection'' are called local Trivializations for the fiber bundle . In other words, lookslike the product (at least locally), except that the fibers for may be a bit ``twisted.''


Examples of fiber bundles include any product (which is a bundle over with Fiber ), theMöbius Strip (which is a fiber bundle over the Circle with Fiber given by the unitinterval [0,1]; i.e, the Base Space is the Circle), and (which is a bundle over withfiber ). A special class of fiber bundle is the Vector Bundle, in which the Fiber is aVector Space.
