【 摘 要 】

We study the energy decay for a variable-coefficient wave equation with memory type acoustic boundary conditions. Boundary memory is described by an integral term. Applying the Riemannian geometry method, we obtain the uniform energy decay under some conditions on the memory function and the coefficient matrix. (C) 2015 Published by Elsevier Inc.
