www.math.columbia.edugeneral a vector bundle can be thought of as a family of vector spaces of the same dimension, parametrized by the base space. For the special case where the vector spaces are of dimension one, a vector bundle is called a \line bundle". 2 Induced Representations Unlike principal bundles, vector bundles always have sections.

www.math.lsu.eduIn these notes, all vector bundles will be smooth. We may denote a vector bundle by ˇ: E! M(and suppress the vector space) or as E. If the dimension of the vector space is mthen the bundle is often called an m-plane bundle. A 1-plane bundle is also called a line bundle. A bundle over a manifold is trivial if it is simply the Cartesian product of
