Fractional partial random differential equations with infinite delay
Results 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 ...

Asymptotic Stability of Differential Equations with Infinite Delay [PDF]
Journal of Applied Mathematics, 2012 A theorem on asymptotic stability is obtained for a differential equation with an infinite delay in a function space which is suitable for the numerical computation of the solution to the infinite delay equation.

A maximum principle for infinite horizon delay equations [PDF]
SIAM Journal on Mathematical Analysis, 2012 We prove a maximum principle of optimal control of stochastic delay equations on infinite horizon. We establish first and second sufficient stochastic maximum principles as well as necessary conditions for that problem.

Semigroups on Frechet spaces and equations with infinite delays [PDF]
Proceedings Mathematical Sciences, 2007 In this paper, we show existence and uniqueness of a solution to a functional differential equation with infinite delay. We choose an appropriate Frechet space so as to cover a large class of functions to be used as initial functions to obtain existence ...

SEIR epidemiological model with varying infectivity and infinite delay [PDF]
Mathematical Biosciences and Engineering, 2008 A new SEIR model with distributed infinite delay is derived whenthe infectivity depends on the age of infection. The basic reproduction numberR0, which is a threshold quantity for the stability of equilibria, is calculated.If $R_0$ 1, then an ...
