Non-homogeneous Dirichlet-transmission problems for the anisotropic Stokes and Navier-Stokes systems in Lipschitz domains with transversal interfaces

Mirela Kohr, Sergey E. Mikhailov, Wolfgang L. Wendland

This paper is build around the stationary anisotropic Stokes and Navier-Stokes systems with an $L^{\infty}$ -tensor coefficient satisfying an ellipticity condition in terms of symmetr…

Variational approach for layer potentials of the Stokes system with $L_{\infty}$ symmetrically elliptic coefficient tensor and applications to Stokes and Navier-Stokes boundary problems

Mirela Kohr, Sergey E. Mikhailov, Wolfgang L. Wendland

The first aim of this paper is to develop a layer potential theory in $L_{2}$ -based weighted Sobolev spaces on Lipschitz bounded and exterior domains of $R^{n}$ , $n \geq 3$ , f…

Potentials and transmission problems in weighted Sobolev spaces for anisotropic Stokes and Navier-Stokes systems with $L_{\infty}$ strongly elliptic coefficient tensor

Mirela Kohr, Sergey E. Mikhailov, Wolfgang L. Wendland

We obtain well-posedness results in $L_{p}$ -based weighted Sobolev spaces for a transmission problem for anisotropic Stokes and Navier-Stokes systems with $L_{\infty}$ strongly ellip…

Newtonian and single layer potentials for the Stokes system with $L^{\infty}$ coefficients and the exterior Dirichlet problem

Mirela Kohr, Sergey E. Mikhailov, Wolfgang L. Wendland

A mixed variational formulation of some problems in $L^{2}$ -based Sobolev spaces is used to define the Newtonian and layer potentials for the Stokes system with $L^{\infty}$ coeffici…

Minimal energy problems for strongly singular Riesz kernels

Helmut Harbrecht, Wolfgang L. Wendland, Natalia Zorii

We study minimal energy problems for strongly singular Riesz kernels on a manifold. Based on the spatial energy of harmonic double layer potentials, we are motivated to formulate t…
