n (category theory) Given a diagram F : J → C, a cone consists of an object N of C, together with a family of morphisms ψ_X : N → F(X) indexed by all of the objects of J, such that for every morphism f : X → Y in J, $F(f)\; \backslash circ\; \backslash psi\_X\; =\; \backslash psi\_Y$. Then N is the vertex of the cone, whose sides are all the ψ_X 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).
