چکیده

In this paper we consider the problem of constructing a well-posed state space model for a class of singular integro-diierential equations of neutral type. The work is motivated by the need to develop a framework for the analysis of numerical methods for designing control laws for aeroelastic and other uid/structure systems. Semigroup theory is used to establish existence and well-posedness results for initial data in weighted L 2 ?spaces. It is shown that these spaces lead naturally to the dissipativeness of the basic dynamic operator. The dissipativeness of the solution generator combined with the Hilbert space structure of these weighted spaces make this choice of a state space more suitable for use in the design of computational methods for control than previously used product spaces.

Optimal Feedback Control of Fractional Semilinear Integro-differential Equations in The Banach Spaces

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 ...

Well-posedness and asymptotics of some nonlinear integro-differential equations

We will prove the well-posedness of certain second order ordinary and partial integro-differential equations with an integral term of the form t ∫ 0 m(φ(t−s))φ̇(s) ds, wherem is given and φ is the solution. The new aspect is the dependence of the kernel on the solution. In addition, for the ordinary integro-differential equation, the asymptotic behaviour of the solution is described for some ker...

University of Cambridge Integro-diierential Equations and Generalized Hypergeometric Functions Integro-diierential Equations and Generalized Hypergeometric Functions Are Neither Zero nor a Negative In- Teger, and 2 0; 2) There Exist Smooth Functions and Such That the Generalized Hypergeometric Function

This paper is concerned with the integro-diierential equations y 0 (t) = ay(t) + Z 1 0 y(qt) d(q) + Z 1 0 y 0 (qt) d(q); t 0 and y(t) + Z 1 0 y(qt) d(q) + Z 1 0 y 0 (qt) d(q) = 0; t 0; where a is a complex constant, while and are complex-valued functions of bounded variation on 0; 1]. The main motivation for the study of these two equations is that for every integers B + 1 A 0 and real constant...

Existence and uniqueness of the solution for a general system of operator equations in $b-$metric spaces endowed with a graph

The purpose of this paper is to present some coupled fixed point results on a metric space endowed with two $b$-metrics. We shall apply a fixed point theorem for an appropriate operator on the Cartesian product of the given spaces endowed with directed graphs. Data dependence, well-posedness and Ulam-Hyers stability are also studied. The results obtained here will be applied to prove the existe...
