14. (category theory) Given a diagram F : J → C, a cone consists of an object N of C, together with a family of morphisms ψX : N → F(X) indexed by all of the objects of J, such that for every morphism f : X → Y in J, F(f) ° ψ_X = ψ_Y . Then N is the vertex of the cone, whose sides are all the ψX indexed by Ob(J) and whose base is F. The cone is said to be "from N to F" and can be denoted as (N, ψ).
