Abstract:
In this paper, we consider the following nonlinear wave equation with variable exponents: \[ u_{tt}-\text \Delta u+|u_t|^{m(\cdot)-2}u_t=0.\] By using a lemma by Komornik, we prove the decay estimates for the solution under suitable assumptions on the variable exponents $m$ and the initial data
