Existence and decay of finite energy solutions for semilinear dissipative wave equations in time-dependent domains [PDF]

open access: yesOpuscula Mathematica, 2020
We consider the initial-boundary value problem for semilinear dissipative wave equations in noncylindrical domain \(\bigcup_{0\leq t \lt\infty} \Omega(t)\times\{t\} \subset \mathbb{R}^N\times \mathbb{R}\). We are interested in finite energy solution.

Decay rates for a coupled viscoelastic Lamé system with strong damping

open access: yesMathematical Modelling and Analysis, 2020
In [6] Beniani, Taouaf and Benaissa studied a coupled viscoelastic Lamé system with strong dampings and established a general decay result. In this paper, we continue to study the system.
