Let α be a differential form defined on an open set D ⊂ . If (D) is a class of functions defined on D, then we say that the differential form α is in this class provided that αi1···ik ∈ (D). For instance, the differential form α is in the class Lp(D) if all its coefficients are in this class. A differential form α of degree k on the manifold with coefficients αi1···ik ∈ L loc( ) is called weakly closed if for each differential form β, degβ = k+1, with compact support suppβ = {m∈ : β = 0} in and with coefficients in the classW q,loc( ), 1/p+1/q = 1, 1≤ p, q ≤∞, we have
