Differential functional von Foerster equations with renewal

open access: yesCondensed Matter Physics, 2008
Natural iterative methods converge to the exact solution of a differential-functional von Foerster-type equation which describes a single population dependent on its past time and state densities as well as on its total size.

Analytic solutions for iterative functional differential equations

open access: yesElectronic Journal of Differential Equations, 2012
Because of its technical difficulties the existence of analytic solutions to the iterative differential equation $x'(z)=x(az+bx(z)+c x'(z))$ is a source of open problems.

Newton's method for stochastic functional differential equations

open access: yesElectronic Journal of Differential Equations, 2012
In this article, we apply Newton's method to stochastic functional differential equations. The first part concerns a first-order convergence. We formulate a Gronwall-type inequality which plays an important role in the proof of the convergence theorem

Approximate controllability of quasilinear functional differential equations

open access: yesElectronic Journal of Differential Equations, 2019
In this article, we study the approximate controllability for quasilinear differential equations with deviating arguments in a Hilbert space. We establish sufficient conditions for the existence of a mild solution. We also obtain sufficient conditions

Special solutions of neutral functional differential equations

open access: yesJournal of Inequalities and Applications, 2001
For a system of nonlinear neutral functional differential equations we prove the existence of an -parameter family of "special solutions" which characterize the asymptotic behavior of all solutions at infinity.

Uniform Stability and Boundedness of a Kind of Third Order Delay Differential Equations

open access: yesBulletin of Computational Applied Mathematics, 2014
By constructing a Lyapunov functional, we obtain some sufficient conditions which guarantee the stability and boundedness of solutions for some nonlinear differential equations of third order with delay.
