Resolvent of nonautonomous linear delay functional differential equations

open access: yesNonautonomous Dynamical Systems, 2015
The aim of this paper is to give a complete proof of the formula for the resolvent of a nonautonomous linear delay functional differential equations given in the book of Hale and Verduyn Lunel [9] under the assumption alone of the continuity of the right-

Classical Theory of Linear Multistep Methods for Volterra Functional Differential Equations

open access: yesDiscrete Dynamics in Nature and Society, 2021
Based on the linear multistep methods for ordinary differential equations (ODEs) and the canonical interpolation theory that was presented by Shoufu Li who is exactly the second author of this paper, we propose the linear multistep methods for general ...

Unique Solvability of the Initial-Value Problem for Fractional Functional Differential Equations—Pantograph-Type Model

open access: yesFractal and Fractional, 2023
Contrary to the initial-value problem for ordinary differential equations, where the classical theory of establishing the exact unique solvability conditions exists, the situation with the initial-value problem for linear functional differential ...

Linear stochastic differential equations with functional boundary conditions [PDF]

open access: yes, 2002
We consider linear n-th order stochastic differential equations on [0,1], with linear boundary conditions supported by a finite subset of [0,1]. We study some features of the solution to these problems, and especially its conditional independence ...

Linear Multistep Methods for Functional Differential Equations [PDF]

open access: yesMathematics of Computation, 1987
The author discusses linear multistep methods for functional differential equations which are correct for the jumps in the derivatives of the solution. The asymptotic behavior of the global discretization error is discussed as well as the implementation of these methods in predictor- corrector mode with step changing strategy based on the estimation of

Existence of Nonnegative Solutions of Linear Autonomous Functional Differential Equations

open access: yesMathematics, 2020
It is shown that if we exclude the existence of nontrivial small solutions, then a linear autonomous functional differential equation has a nontrivial nonnegative solution if and only if it has a nonnegative eigenfunction.

Structure Constants in the $N=1$ Super-Liouville Field Theory [PDF]

open access: yes, 1996
The symmetry algebra of $N=1$ Super-Liouville field theory in two dimensions is the infinite dimensional $N=1$ superconformal algebra, which allows one to prove, that correlation functions, containing degenerated fields obey some partial linear ...

Reduction of Linear Functional Systems using Fuhrmann's Equivalence

open access: yesSultan Qaboos University Journal for Science, 2016
Functional systems arise in the treatment of systems of partial differential equations, delay-differential equations, multidimensional equations, etc. The problem of reducing a linear functional system to a system containing fewer equations and unknowns ...

On Fundamental Solution for Autonomous Linear Retarded Functional Differential Equations

open access: yesMathematics, 2020
This document focuses attention on the fundamental solution of an autonomous linear retarded functional differential equation (RFDE) along with its supporting cast of actors: kernel matrix, characteristic matrix, resolvent matrix; and the Laplace ...

Linear functional differential equations with Property A

open access: yesJournal of Mathematical Analysis and Applications, 2003
The paper deals with oscillatory properties of the linear functional- differential equation \[ u^{(n)}(t)+ \sum^m_{i=1} \int^{\sigma_i(t)}_{\tau_i(t)} u(s)\,d_s r_i(s, t)= 0, \] where \(n\geq 2\), \(\tau_i(t)\leq \sigma_i(t)\), \(\tau_i(t)\to \infty\) for \(t\to\infty\) and the functions \(r_i\) are nondecreasing in the first argument and Lebesgue ...
