Abstract
In this work, we present some of the theories of semigroups and global attractors. Also, we present process of evolution and pullback attractors. Finally, we show the existence and regularity of the pullback attractor for the problem $u_{tt} +\beta(t)u_t = \Delta u + f(u)$ in a bounded smooth domain $ \Omega \subset \mathbb{R}^n$ with the Dirichlet boundary conditions, the damping $\beta:\mathbb{R}\longrightarrow (0,+\infty)$ is a suitable function and $f \in C^2(\mathbb{R})$ is a nonlinear function with a dissipative condition.
