Improved Delay Estimates for a Queueing Model for Random Linear Coding for Unicast [PDF]

open access: yes, 2009
Consider a lossy communication channel for unicast with zero-delay feedback. For this communication scenario, a simple retransmission scheme is optimum with respect to delay.

Center manifolds for infinite delay

open access: yesJournal of Differential Equations, 2009
AbstractWe obtain a C1 center manifold theorem for perturbations of delay difference equations in Banach spaces with infinite delay. Our results extend in several directions the existing center manifold theorems. Besides considering infinite delay equations, we consider perturbations of nonuniform exponential trichotomies and generalized trichotomies ...

Fractional partial random differential equations with infinite delay

open access: yesResults in Physics, 2022
The present paper deals with some existence results for the Darboux problem of partial fractional random differential equations with infinite delay. The arguments are based on a random fixed point theorem with stochastic domain combined with the measure ...

Infinite horizon optimal control of forward-backward stochastic differential equations with delay [PDF]

open access: yes, 2013
We consider a problem of optimal control of an infinite horizon system governed by forward-backward stochastic differential equations with delay. Sufficient and necessary maximum principles for optimal control under partial information in infinite ...

Boundedness in infinite delay systems

open access: yesJournal of Mathematical Analysis and Applications, 1989
AbstractWe consider a system of functional differential equations with infinite delay and derive conditions on Liapunov functionals to ensure that solutions are uniformly bounded and uniformly ultimately bounded. The analysis is based on Jensen's inequality. Examples of Volterra integrodifferential equations are given.

On the geometric interpretation of the Polynomial Lie Bracket for nonlinear time-delay systems [PDF]

open access: yes, 2016
Time-delay systems are infinite dimensional, thus standard differential geometric tools can not be applied in a straightforward way. Though, thanks to a suitable extended Lie Bracket - or Polynomial Lie Bracket - which has been introduced recently, it is

Dimensional reduction of nonlinear time delay systems

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2005
Whenever there is a time delay in a dynamical system, the study of stability becomes an infinite-dimensional problem. The centre manifold theorem, together with the classical Hopf bifurcation, is the most valuable approach for simplifying the infinite ...

Optimal Control for Neutral Stochastic Integrodifferential Equations with Infinite Delay Driven by Poisson Jumps and Rosenblatt Process

open access: yesFractal and Fractional, 2023
In this paper, we investigate the optimal control problems for a class of neutral stochastic integrodifferential equations (NSIDEs) with infinite delay driven by Poisson jumps and the Rosenblat process in Hilbert space involving concrete-fading memory ...

Distribution of Wigner delay time from single channel disordered systems [PDF]

open access: yes, 1997
We consider the scattering of an electron from a semi-infinite one-dimensional random medium. The random medium is characterized by force, $-\d V/\d L$ being the basic random variable.
