چکیده
In this paper the long time asymptotic behavior of solutions of semilinear symmetric hyperbolic system including Maxwell s equations and the scalar wave equation in an ar bitraty domain are investigated The possibly nonlinear damping term may vanish on a certain subset of the domain It is shown that the solution decays weakly to zero if and only if the initial state is orthogonal to all stationary states In the case that the nonlinear damping is in addition montone also strong local L convergence is shown AMS B Q L L A Introduction The subject of this paper the long time asymptotic behavior of solutions of semilinear hyperbolic systems of the form

Local Solvability and Regularity Results for a Class of Semilinear Elliptic Problems in Nonsmooth Domains
We consider a class of semilinear elliptic problems in twoand three-dimensional domains with conical points. We introduce Sobolev spaces with detached asymptotics generated by the asymptotical behaviour of solutions of corresponding linearized problems near conical boundary points. We show that the corresponding nonlinear operator acting between these spaces is Fréchet differentiable. Applying ...
متن کاملSome Common Asymptotic Properties of Semilinear Parabolic, Hyperbolic and Elliptic Equations
We consider three types of semilinear second order PDEs on a cylindrical domain Ω × (0,∞), where Ω is a bounded domain in N , N 2. Among these, two are evolution problems of parabolic and hyperbolic types, in which the unbounded direction of Ω × (0,∞) is reserved for time t, the third type is an elliptic equation with a singled out unbounded variable t. We discuss the asymptotic behavior, as t ...

Recently, there has been significant development in the existence of mild solutions for fractional semilinear integro-differential equations but optimal control is not provided. The aim of this paper is studying optimal feedback control for fractional semilinear integro-differential equations in an arbitrary Banach space associated with operators ...
متن کاملNonlinear Stability of Travelling Waves for a Hyperbolic System with Relaxation
We investigate the existence and the asymptotic stability of travelling wave solutions for a hyperbolic 2 2 system with a relaxation source term. Using the subcharacteristic stability condition, which implies special monotonicity properties of the solutions, we are able to establish the L 1 asymptotic attractivity of these solutions. In this paper we investigate nonlinear stability of travellin...
متن کاملDetermining nodes for semilinear parabolic equations
We discuss the uniqueness of the equilibria of time-global solutions of general semilinear parabolic equations by a finite set of values of these solutions. More precisely, if the asymptotic behaviour of a time-global solution is known on an appropriate finite set, then the asymptotic behaviour of a time-global solution itself is entirely determined in a domain.
