Webn≥ 3, is an open, bounded set such that ∂Ω is Lipschitz, then Equation (1) has a unique solution in Ws,p(Ω) depending continuously on f∈ Ws−2,p(Ω) if, and only if, (1/p,s) belongs to a certain explicit hexagon. They also prove a similar result if Ω ⊂ R2. A consequence of this result is that the smoothness of the Web5 de set. de 2024 · The open ball in R with center a ∈ R and radius δ > 0 is the set B(a; δ) = (a − δ, a + δ).

If a set S in R n is bounded, then it can be enclosed within an n-box = [,] where a > 0. By the lemma above, it is enough to show that T 0 is compact. Assume, by way of contradiction, that T 0 is not compact.
