چکیده
We obtain estimates for Dirichlet eigenvalues of divergence form elliptic operators −div [A(z)∇f(z)] in bounded non-Lipschitz domains. propose a method based on the quasiconformal composition Sobolev spaces with application to weighted Poincaré–Sobolev inequalities.

Half-Dirichlet problems for Dirac operators in Lipschitz domains
Recall that in the case of the Dirichlet problem for the Laplace operator ∂2 x +∂ 2 y in Ω ⊆ R2, one prescribes the whole trace of a harmonic function in, say, L2(∂Ω). On the other hand, for the Cauchy-Riemann operator ∂x + i∂y, natural boundary problems are obtained by prescribing “half” of the trace of the analytic function in L2(∂Ω). Such half-Dirichlet problems arise when, for example, one ...
متن کاملMonotone Numerical Schemes for a Dirichlet Problem for Elliptic Operators in Divergence Form
We consider a second order differential operator A( ) = − ∑d i,j=1 ∂iaij( )∂j + ∑d j=1 ∂j ( bj( )· ) +c( ) on R, on a bounded domain D with Dirichlet boundary conditions on ∂D, under mild assumptions on the coefficients of the diffusion tensor aij . The object is to construct monotone numerical schemes to approximate the solution of the problem A( )u( ) = μ( ), ∈ D, where μ is a positive Radon ...
متن کاملDivergence form operators in Reifenberg flat domains
We study the boundary regularity of solutions of elliptic operators in divergence form with C coefficients or operators which are small perturbations of the Laplacian in non-smooth domains. We show that, as in the case of the Laplacian, there exists a close relationship between the regularity of the corresponding elliptic measure and the geometry of the domain.

متن کاملAnalyticity of Dirichlet-Neumann Operators on Hölder and Lipschitz Domains
In this paper we take up the question of analyticity properties of Dirichlet–Neumann operators with respect to boundary deformations. In two separate results, we show that if the deformation is sufficiently small and lies either in the class of C1+α (any α > 0) or Lipschitz functions, then the Dirichlet–Neumann operator is analytic with respect to this deformation. The proofs of both results ut...
