- Title
Local Energy Decay of Coupled Wave Equations in Exterior Domain.
- Authors
WU Jieqiong; WU Jiangtao
- Abstract
The local energy decay of wave equations in an exterior domain coupled by the displacement was studied. Assume that the two wave systems were coupled in a neighborhood of the boundary and the dampings of the system were exerted only in a bounded domain. The decay estimate of local energy for the coupled system was obtained by using multiplier method,weighted function method and the cut-off technology.
