On the Dirichlet problem on Lorentz and Orlicz spaces with applications to Schwarz-Christoffel domains
It is known (see [14]) that, for every Lipschitz domain on the plane Ω = {x + iy : y > ν(x)}, with ν a real valued Lipschitz function, there exists 1 ≤ p0 < 2 so that the Dirichlet problem has a solution for every function f ∈ Lp(ds) and every p ∈ (p0,∞). Moreover, if p0 > 1, the result is...

| Sumario: | It is known (see [14]) that, for every Lipschitz domain on the plane Ω = {x + iy : y > ν(x)}, with ν a real valued Lipschitz function, there exists 1 ≤ p0 < 2 so that the Dirichlet problem has a solution for every function f ∈ Lp(ds) and every p ∈ (p0,∞). Moreover, if p0 > 1, the result is false for every p ≤ p0. The purpose of this paper is to study in more detail what happens at the endpoint p0; that is, we want to find spaces X ⊂ Lp0 so that the Dirichlet problem is solvable for every f ∈ X. These spaces X will be either the Lorentz space Lp0,1(ds) or some type of logarithmic Orlicz space. Our results will be applied to the special case of Schwarz–Christoffel Lipschitz domains, among others, for which we explicitly compute the value of p0. |
