Abstract

A local energy decay problem is studied to a typical linear wave equation in an exterior domain. For this purpose, we do not assume any compactness of the support on the initial data. This generalizes a previous famous result due to Morawetz (Comm. Pure Appl. Math. 1961; 14:561–568). In order to prove local energy decay we mainly apply two types of new ideas due to Ikehata–Matsuyama (Sci. Math. Japon. 2002; 55:33–42) and Todorova–Yordanov (J. Differential Equations 2001; 174:464). Copyright © 2004 John Wiley & Sons, Ltd.

## Abstract We study a decay property of solutions for the wave equation with a localized dissipation and a boundary dissipation in an exterior domain Ω with the boundary ∂Ω = Γ~0~ ∪ Γ~1~, Γ~0~ ∩ Γ~1~ = ∅︁. We impose the homogeneous Dirichlet condition on Γ~0~ and a dissipative Neumann condition on

## Abstract Suppose __u__ is the solution of the initial value problem Suppose __n__ ≥ 1 is odd, __f__ and __g__ are supported in a ball __B__ with boundary __S__, and one of __f__ or __g__ is zero. We derive identities relating the norm of __f__ or __g__ to the norm of the trace of __u__ on __S_
