Regularity of the global attractor for semilinear damped wave equations
utt + 2ηA 1 2 ut + aut + Au = f(u) in H1 0 (Ω)×L2(Ω), where Ω is a bounded smooth domain in R3. For dissipative nonlinearity f ∈ C2(R,R) satisfying |f ′′(s)| ≤ c(1 + |s|) with some c > 0, we prove that the family of attractors {Aη , η ≥ 0} is upper semicontinuous at η = 0 in H1+s(Ω)×Hs(Ω) for any s ∈ (0, 1). For dissipative f ∈ C3(R,R) satisfying lim|s|→∞ f ′′(s) s = 0 we prove that the attract...
متن کاملDimension of the Attractor for 3d Flow of Non-newtonian Fluid
We consider the equations of an incompressible, homogeneous fluid, occupying a bounded domain in R. The stress tensor has a general polynomial dependence on the symmetric velocity gradient. Our goal is to estimate the dimension of the global attractor in terms of the relevant physical constants.
متن کاملThe existence of global attractor for a Cahn-Hilliard/Allen-Cahn equation
In this paper, we consider a Cahn-Hillard/Allen-Cahn equation. By using the semigroup and the classical existence theorem of global attractors, we give the existence of the global attractor in H^k(0
متن کاملUpper Semicontinuity of the Attractor for Lattice Dynamical Systems of Partly Dissipative Reaction-diffusion Systems
Lattice dynamical systems arise in various application fields, for instance, in chemical reaction theory, material science, biology, laser systems, image processing and pattern recognition, and electrical engineering (cf. [6, 7, 13]). In each field, they have their own forms, but in some other cases, they appear as spatial discretizations of partial differential equations (PDEs). Recently, many...
متن کاملGlobal attractor for a nonlocal hyperbolic problem on ${mathcal{R}}^{N}$
We consider the quasilinear Kirchhoff's problem$$ u_{tt}-phi (x)||nabla u(t)||^{2}Delta u+f(u)=0 ,;; x in {mathcal{R}}^{N}, ;; t geq 0,$$with the initial conditions $ u(x,0) = u_0 (x)$ and $u_t(x,0) = u_1 (x)$, in the case where $N geq 3, ; f(u)=|u|^{a}u$ and $(phi (x))^{-1} in L^{N/2}({mathcal{R}}^{N})cap L^{infty}({mathcal{R}}^{N} )$ is a positive function. The purpose of our work is to ...
