Abstract
Given a cellular complex consisting of polytopes, embedded in a Euclidean space, we construct finite element spaces of differential forms, conforming with respect to the exterior derivative, containing those that are polynomial of given maximal degree, having locally the property of exact sequence and extension, so that among all spaces having these properties they have the smallest dimension. More generally we construct, for any finite element system included in a compatible finite element system, an intermediate compatible finite element system of minimal dimension.
