    Discovered this old entry. Have removed the following first sentence

    In the context of families of algebraic varieties, the cohomology classes vary with families in a way which induces a specific kind of flat connections.

    and replaced it by the following:


    Under the identification of local systems (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).
