✦ Synopsis

A non-overlapping domain decomposition method with adaptive interface conditions is applied to parabolic initial-boundary value problems in the full range from diffusion-to advection-dominated problems. The basic discretizations are the discontinuous Galerkin method in time and a stabilized Galerkin method in space.

A convergence proof is available in appropriate Sobolev norms for the continuous elliptic problems arising in each time step. The numerical convergence rate is independent of the mesh size. Finally we extend the approach to more complex problems.

this paper, we present a domain decomposition method, based on the general theory of Steklov-Poincare operators, for a class of linear exterior boundary value problems arising in potential theory and heat conductivity. We first use a Dirichlet-to-Neumann mapping, derived from boundary integral equat

## Abstract Non‐overlapping domain decomposition techniques are used to solve the finite element equations and to couple them with a boundary element method. A suitable approach dealing with finite element nodes common to more than two subdomains, the so‐called cross‐points, endows the method with
