Parabolic Evolution Equations with Asymptoticallyautonomous

نویسنده

  • Roland Schnaubelt
چکیده

We study retarded parabolic non{autonomous evolution equations whose coeecients converge as t ! 1 such that the autonomous problem in the limit has an exponential dichotomy. Then the non{autonomous problem inherits the exponential dichotomy and the solution of the inhomogeneous equation tends to the stationary solution at innnity. We use a generalized characteristic equation to deduce the exponential dichotomy and new representation formulas for the solution of the inhomogeneous equation. 1. Introduction In the present paper we continue the investigation of the long{term behaviour of asymp-totically autonomous evolution equations begun in 30]. There we studied the Cauchy problem _

Quasilinear Parabolic Functional Evolution Equations

Based on our recent work on quasilinear parabolic evolution equations and maximal regularity we prove a general result for quasilinear evolution equations with memory. It is then applied to the study of quasilinear parabolic differential equations in weak settings. We prove that they generate Lipschitz semiflows on natural history spaces. The new feature is that delays can occur in the highest ...

Covariance Structure of Parabolic Stochastic Partial Differential Equations

In this paper parabolic random partial differential equations and parabolic stochastic partial differential equations driven by a Wiener process are considered. A deterministic, tensorized evolution equation for the second moment and the covariance of the solutions of the parabolic stochastic partial differential equations is derived. Well-posedness of a space-time weak variational formulation ...

Backward uniqueness of stochastic parabolic like equations driven by Gaussian multiplicative noise

One proves here the backward uniqueness of solutions to stochastic semilinear parabolic equations and also for the tamed Navier–Stokes equations driven by linearly multiplicative Gaussian noises. Applications to approximate controllability of nonlinear stochastic parabolic equations with initial controllers are given. The method of proof relies on the logarithmic convexity property known to hol...

Strong Convergence of Solutions to Nonautonomous Kolmogorov Equations

We study a class of nonautonomous, linear, parabolic equations with unbounded coefficients on Rd which admit an evolution system of measures. It is shown that the solutions of these equations converge to constant functions as t → +∞. We further establish the uniqueness of the tight evolution system of measures and treat the case of converging coefficients.

Evolution Equations of Parabolic Type

be linear and quasilinear evolution equations of parabolic type in a Banach space X respectively. By "parabolic type" we mean that A(t) and A(t,u) are all the infinitesimal generators of analytic linear semigroups on X we do not necessarily assume that the domains of the operators A(t) and A("t,u) are dense subspaces of X, so the semigroups generated by them may not be of class c0 J. The domain...
