They generalize the familiar notion of a covering space in homotopy theory, and also relate to the notion of a sheaf in algebraic geometry. section s is a continuous map s: B → E such that p ◦ s = identity: B → B.

Then the fiber of π over p ∈ M is the inverse image π−1(p) ∈ E. In some cases, as in the context of fiber bundles, it it convenient to denote the fiber π−1(p) as Ep.
