On the density of classes of closed convex sets with pointwise constraints in Sobolev spaces
Hintermüller, M.; Rautenberg, C.N.
For a Banach space X of R^M-valued functions on a Lipschitz domain, let K(X) ⊂ X be a closed convex set arising from pointwise constraints on the value of the function, its gradient or its divergence, respectively. The ...
