In mathematics, a vector bundle is a topological construction that makes precise the idea of a family of vector spaces parameterized by another space ๐‘‹ (for example ๐‘‹ could be a topological space, a manifold, or an algebraic variety): to every point ๐‘ฅ of the space ๐‘‹ we associate (or "attach") a vector space ๐‘‰ ( ๐‘ฅ ) in such a way that these vector spaces fit together to form another space of the same kind as ๐‘‹ (e.g. a topological space, manifold, or algebraic variety), which is then called a vector bundle over ๐‘‹ . The simplest example is the case that the family of vector spaces is constant, i.e., there is a fixed vector space ๐‘‰ such that ๐‘‰ ( ๐‘ฅ ) = ๐‘‰ for all ๐‘ฅ in ๐‘‹ : in this case there is a copy of ๐‘‰ for each ๐‘ฅ in ๐‘‹ and these copies fit together to form the vector bundle ๐‘‹ ร— ๐‘‰ over ๐‘‹ . Such vector bundles are said to be trivial. A more complicated (and prototypical) class of examples are the tangent bundles of smooth (or differentiable) m

Locally around every point in S 1 {\displaystyle {\mathcal {S}}^{1}} , it looks like U ร— R {\displaystyle U\times \mathbb {R} } (where U {\displaystyle U} is an open arc including the point), but the total bundle is different from S 1 ร— R {\displaystyle {\mathcal {S}}^{1}\times \mathbb {R} } (which is a cylinder instead).
