Pullback Attractors for a Critical Degenerate Wave Equation with Time-dependent Damping
Dandan Li, Qingquan Chang, Chunyou Sun
The aim of this paper is to analyze the long-time dynamical behavior of the solution for a degenerate wave equation with time-dependent damping term $\partial_{tt}u + β(t)\partial_…

Deterministic and random attractors for a wave equation with sign changing damping
Qingquan Chang, Dandan Li, Chunyou Sun +1
The paper gives a detailed study of long-time dynamics generated by weakly damped wave equations in bounded 3D domains where the damping exponent depends explicitly on time and may…
