Abstract:We study necessary and sufficient conditions for the existence of solutions in $$W^{1,infty}_0 (Omega; Lambda^{k}(mathbb{R}^n))$$ of the problem $${rm d}omega (x)in E,quad text{a.e. in }Omega$$ where $$EsubseteqLambda^{k+1}(mathbb{R}^{n})$$ is a given set. Special attention is given to the case of the curl (i.e. k = 1), particularly in dimension 3. Some applications to the calculus of variations are also stated.
