چکیده
The paper addresses a kind of non-autonomous nonlocal parabolic equations when the external force contains hereditary characteristics involving bounded and unbounded delays. First, well-posedness problem is analyzed by Galerkin method energy estimations in phase space C ? ( X ) . Moreover, some results related to strong solutions are proved under suitable assumptions. existence stationary then established corollary Brower fixed point theorem. By constructing appropriate Lyapunov functionals terms characteristic delay terms, deep analysis on stability attractiveness established. Furthermore, pullback attractors L 2 ? , with delays, shown. We emphasize that, prove case, new space, E ? has be constructed.

Semilinear Nonlocal Differential Equations with Delay Terms
The goal of this paper is to obtain the regularity and the existence of solutions of a retarded semilinear differential equation with nonlocal condition by applying Schauder’s fixed point theorem. We construct the fundamental solution, establish the Hölder continuity results concerning the fundamental solution of its corresponding retarded linear equation, and prove the uniqueness of solutions ...

Periodic perturbations with delay of autonomous differential equations on manifolds
We apply topological methods to the study of the set of harmonic solutions of periodically perturbed autonomous ordinary differential equations on differentiable manifolds, allowing the perturbing term to contain a fixed delay. In the crucial step, in order to cope with the delay, we define a suitable (infinite dimensional) notion of Poincaré T -translation operator and prove a formula that, in...
متن کاملStability and boundedness for a kind of non-autonomous differential equations with constant delay
We establish some new sufficient conditions to the uniform asymptotically stability and boundedness of the solutions for a kind of non-autonomous differential equations of third order with constant delay. By defining an appropriate Lyapunov functional, we prove two new theorems on the subject. Our results improve and form a complement to some known recent results in the literature.
