It is shown that higher degree exact differential forms on compact Riemannian n-manifolds possess continuous primitives whose uniform norm is controlled by their L^n norm. A contact sub-Riemannian analogue is proven, with differential forms replaced with Rumin differential forms.

Abstract
It is shown that higher degree exact differential forms on compact Riemannian n-manifolds possess continuous primitives whose uniform norm is controlled by their L^n norm. A contact sub-Riemannian analogue is proven, with differential forms replaced with Rumin differential forms.File in questo prodotto:
