Global attractors for a nonlinear viscoelastic equations with strong damping velocity-dependent material density

  • Suli Zhang

摘要

In this paper, we study the long-time behavior of the semigroup  S ( t ) $S(t)$  generated by a nonlinear viscoelastic equation with strong damping in a bounded domain Ω of  R N $\mathbb{R}^{N}$ . We prove the well-posedness and the existence of the global attractor associated to this problem.
