Abstract
This paper is concerned with the asymptotic stability and instability of
solutions to a variable coefficient logarithmic wave equation with
nonlinear damping and memory term. This model describes wave travelling
through nonhomogeneous viscoelastic materials. By choosing appropriate
multiplier and using weighted energy method, we prove the exponential
decay of the energy. Besides, we also obtain the instability at the
infinity of the solutions in the presence of the nonlinear damping.03 Aug 2021Submitted to Mathematical Methods in the Applied Sciences 04 Aug 2021Submission Checks Completed
