We study the asymptotic behavior of solutions of a stochastic time-dependent damped wave equation. With the critical growth restrictions on the nonlinearity \begin{document}$ f $\end{document} and the time-dependent damped term, we prove the global e

We investigate the longtime dynamical behavior of 2D Navier–Stokes equations with a moving boundary. We obtain the well-posedness and dissipation through the penalty method. Then, we derive the regularity by applying a new penalty. Finally, we show

In this paper we consider the long-time behavior of a class of stochastic degenerate parabolic equations involving an operator which is X -elliptic with respect to a family of locally Lipschitz continuous vector fields X = { X 1 , X 2 , … , X m ˜

We explore the convergence of the global attractors for a class of perturbed severely damped wave equations with the Dirichlet boundary condition in the 3D bounded domain. With respect to the perturbation parameter, it is shown that the global attrac

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 ∂ t t u + β ( t ) ∂ t u = L u ( x , t ) + f ( u ) on a bounded domain Ω ⊂ R N with Dirichlet

In this paper, a new variant of feedforward neural networks has been proposed for a class of nonsmooth optimization problems. The penalty term of the presented neural networks stems from the Group Lasso method which selects hidden variables in a grou
