## Abstract The theory for coupling of mapped wave infinite elements and special wave finite elements for the solution of the Helmholtz equation in unbounded domains is presented. Mapped wave infinite elements can be applied to boundaries of arbitrary shape for exterior wave problems without trunca
We consider the equations of motion of compressible viscous fluid in an exterior domain in R 3 : We give the L q Γ L p estimates for solutions to the linearized equations and show an optimal decay estimate for solutions to the nonlinear problem. In particular, we shall give L 1 estimates, which impl
This paper contains a first systematic analysis of a posteriori estimation for finite element solutions of the Helmholtz equation. In this first part, it is shown that the standard a posteriori estimates, based only on local computations, severely underestimate the exact error for the classes of wav
