On basin of zero-solutions to a semilinear parabolic equation with Ornstein-Uhlenbeck operator

open access: yesJournal of Inequalities and Applications, 2006
We consider the basin of the zero-solution to a semilinear parabolic equation on with the Ornstein-Uhlenbeck operator. Our aim is to show that the Ornstein-Uhlenbeck operator contributes to enlargement of the basin by using the logarithmic Sobolev ...

Blow-up of solutions for weakly coupled systems of complex Ginzburg-Landau equations

open access: yes, 2017
Blow-up phenomena ofvweakly coupled systems of several evolution equations, especially complex Ginzburg-Landau equationsvis shown by a straightforward ODE approach not so-called test-function method, which gives the natural blow-up rate.

Pullback attractors for non-autonomous parabolic equations involving Grushin operators

open access: yesElectronic Journal of Differential Equations, 2010
Using the asymptotic a priori estimate method, we prove the existence of pullback attractors for a non-autonomous semilinear degenerate parabolic equation involving the Grushin operator in a bounded domain.

Almost automorphy of semilinear parabolic evolution equations

open access: yesElectronic Journal of Differential Equations, 2008
This paper studies the existence and uniqueness of almost automorphic mild solutions to the semilinear parabolic evolution equation $$ u'(t)=A(t)u(t)+f(t, u(t)), $$ assuming that the linear operators $A(cdot)$ satisfy the Acquistapace-Terreni ...

Classical and weak solutions for semilinear parabolic equations with Preisach hysteresis [PDF]

open access: yesOpuscula Mathematica, 2008
We consider the solvability of the semilinear parabolic differential equation \[\frac{\partial u}{\partial t}(x,t)- \Delta u(x,t) + c(x,t)u(x,t) = \mathcal{P}(u) + \gamma (x,t)\] in a cylinder \(D=\Omega \times (0,T)\), where \(\mathcal{P}\) is a ...
