1. Vector bundle: A vector bundle is a topological space together with a surjective map (the projection) from a paracompact topological space (the base space) to the vector bundle, such that every point in the base space has an open neighborhood for which the preimage is homeomorphic to the product of the neighborhood and a finite-dimensional real vector space.

2. Sheaf of modules: A sheaf of modules is a sheaf where the stalks are modules over a commutative ring instead of a vector space.
