Query: General decay for a viscoelastic wave equation with dynamic boundary
  conditions and a time-varying delay   The goal of this paper is to study a nonlinear viscoelastic wave equation
with strong damping, time-varying delay and dynamical boundary condition. By
introducing suitable energy and Lyapunov functionals, under suitable
assumptions, we then prove a general decay result of the energy, from which the
usual exponential and polynomial decay rates are only special cases.
