Nonlinear hyperbolic volterra integrodifferential equations

Nonlinear Analysis: Theory, Methods & Applications, 1996
The well posedness of the abstract Cauchy problem \[ u'(t) = Au(t) + \int^t_{t_0} K \bigl( t,s,u(s) \bigr) ds + f(t), \quad u(t_0) = u_0 \] is studied, \(A\) denoting a linear Hille-Yosida operator in the Banach space \((X,II \cdot II)\). The paper consists of different Sections, and includes the proof of various theorems. The last Section refers to an

An Integrodifferential Equation

Proceedings of the American Mathematical Society, 1980
The vector equation x'(t) = A(i)x(t) + ('C(t, s)D(x(s))x(s) ds + F(t) is considered in which A is not necessarily a stable matrix, but A(f) + G{t, t)D(0) is stable where G is an antiderivative of C with respect to t. Stability and boundedness results are then obtained. We also point out that boundedness results of Levin for the scalar equation u'(t) = -

Periodic Solutions of Integrodifferential Equations

Journal of the London Mathematical Society, 1985
The author is investigating the existence of periodic solutions to the integrodifferential equation of Volterra type \[ (1)\quad x'(t)=h(t,x(t))+\int^{t}_{-\infty}q(t,s,x(s))ds, \] under the basic assumptions that \(h: R\times R^ n\to R^ n\), and \(q: R\times R\times R^ n\to R^ n\) are both continuous, h is periodic in t with period T, and \(q(t+T,s+T ...

First Order Integrodifferential Equations

1999
In this chapter we shall present a result which establishes the existence of nonnegative solutions of the periodic boundary value problem involving the first order integrodifferential equation, namely, $$\begin{array}{*{20}{c}} {y'(t) = Fy(t) a.e. on [0,T]} \\ {y(0) = y(T)} \\ \end{array}$$ (24.1) where y ∈ C[0,T] and F is given by $$Fy(t)

ON PERTURBED ABSTRACT FUNCTIONAL INTEGRODIFFERENTIAL EQUATION

Acta Mathematica Scientia, 1988
The authors are concerned with the following functional integrodifferential problem: \[ (P)\quad x'(t)+A(t)x(t)=\int^{t}_{0}[a(t,s)g_ 0(s,x_ s)+g_ 1(t,s,x_ s)]ds+ \] \[ +f_ 1(t,x_ t)+f_ 0(t),\quad t\in [0,T],\quad x_ 0=\phi. \] Here A(t) is an m-accretive operator in a Banach space B with domain independent of t, a is a scalar function; \(g_ 0\), \(g_ ...
