Abstract:

In this paper, we study the long-time dynamical behavior of solutions for the nonclassical diffusion equation with time-dependent memory kernel in the time-dependent space $H_{0}^1(\Omega)\times L_{\mu_{t}}^2(\mathbb R^+; H_{0}^1(\Omega))$. Under the new theorical framework, the well-posedness of the solution, the existence and the regularity of the time-dependent global attractors are proved by using the delicate integral estimation method and decomposition technique.

Key words: Nonclassical diffusion equation, Time-dependent memory kernel, Well-posedness, Time-dependent global attractors, Regularity of the attractors
