Oscillation in neutral partial functional differential equations and inequalities [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 1998

Discontinuous solutions of neutral functional differential equations [PDF]

open access: yesPublicacions Matemàtiques, 1993
The fundamental theory of existence, uniqueness and continuous differentiability of Lp-solutions for Neutral Functional Differential Equations is presented. Also, the spectrum of the solution operator of general autonomous linear NFDEs is described. Finally, an extension of Hartman Grobman Theorem on local conjugacy near a hyperbolic equilibrium is ...

Stability of Nonlinear Neutral Stochastic Functional Differential Equations

open access: yesJournal of Applied Mathematics, 2010
Neutral stochastic functional differential equations (NSFDEs) have recently been studied intensively. The well-known conditions imposed for the existence and uniqueness and exponential stability of the global solution are the local Lipschitz condition ...

Neutral stochastic functional differential equations with Lévy jumps under the local Lipschitz condition [PDF]

open access: gold, 2017
In this paper, a general neutral stochastic functional differential equations with infinite delay and Lévy jumps (NSFDEwLJs) is studied. We investigate the existence and uniqueness of solutions to NSFDEwLJs at the phase space Cg under the local ...

Neutral Backward Stochastic Functional Differential Equations and Their Application [PDF]

open access: green, 2013
In this paper we are concerned with a new type of backward equations with anticipation which we call neutral backward stochastic functional differential equations. We obtain the existence and uniqueness and prove a comparison theorem.
