An extension of a theorem of V. Šverák to variable exponent spaces

Abstract

In 1993, V. Šverák proved that if a sequence of uniformly bounded domains Ωn ℝ2 such that Ωn → Ω in the sense of the Hausdorff complementary topology, verify that the number of connected components of its complements are bounded, then the solutions of the Dirichlet problem for the Laplacian with source f ∈ L2(ℝ2) converges to the solution of the limit domain with same source. In this paper, we extend Šverák result to variable exponent spaces.
