(see also *Chern-Weil theory*, parameterized homotopy theory)

A *flat vector bundle* is a vector bundle with connection on a vector bundle which is flat. Specifically a *flat line bundle* is a line bundle with flat connection.

Under the identification of local systems – in the sense of locally constant and locally free abelian sheaves – with flat vector bundles, the flat connection induced on these vector bundles is called the *Gauss-Manin connection* (e.g. Voisin 2002, Def. 9.13).
