Existence results for functional differential inclusions

open access: yesElectronic Journal of Differential Equations, 2001
In this note we investigate the existence of solutions to functional differential inclusions on compact intervals. We use the fixed point theorem introduced by Covitz and Nadler for contraction multi-valued maps.

Generalized Solutions of Functional Differential Inclusions [PDF]

open access: yesAbstract and Applied Analysis, 2008
We consider the initial value problem for a functional differential inclusion with a Volterra multivalued mapping that is not necessarily decomposable in . The concept of the decomposable hull of a set is introduced. Using this concept, we define a generalized solution of such a problem and study its properties.

Existence of solutions for nonconvex functional differential inclusions

open access: yesElectronic Journal of Differential Equations, 2004
We prove the existence of solutions for the functional differential inclusion $x'in F(T(t)x)$, where $F$ is upper semi-continuous, compact-valued multifunction such that $F(T(t)x)subset partial V(x(t))$ on $[0,T]$, $V$ is a proper convex and lower ...

Impulsive neutral functional differential inclusions with variable times

open access: yesElectronic Journal of Differential Equations, 2003
In this paper, we study the existence of solutions for first and second order impulsive neutral functional differential inclusions with variable times. Our main tool is a fixed point theorem due to Martelli for condensing multivalued maps.

Discrete Approximations of a Controlled Sweeping Process [PDF]

open access: yes, 2014
The paper is devoted to the study of a new class of optimal control problems governed by the classical Moreau sweeping process with the new feature that the polyhe- dral moving set is not fixed while controlled by time-dependent functions.

Extremal Solutions of Functional Differential Inclusions

open access: yesJournal of Mathematical Analysis and Applications, 1993
Let \(X\) be a separable Banach space; \({\mathcal K}\subset X\) be a cone and \(v: [-\tau,a]\to X\) be a solution of a problem \(\dot v(t)\in F(t,v_ t)+{\mathcal K}\), \(t\in [0,a]\); \(v_ 0\geq\varphi\), where \(F\) is a Carathéodory type multifunction with convex closed values satisfying the Ambrosetti type regularity condition. The viability result

Existence of solutions of functional differential inclusions [PDF]

open access: yesInternational Journal of Stochastic Analysis, 1992
We prove the existence of solutions of a functional differential inclusion. By using the variation of parameters formula we convert the functional differential inclusion into an integral inclusion and prove the existence of a fixed point of the set‐valued mapping with the help of the Kakutani‐Bohnenblust‐Karlin fixed point theorem.

Controllability of Impulsive Neutral Functional Differential Inclusions in Banach Spaces

open access: yesAbstract and Applied Analysis, 2013
We investigate the controllability of impulsive neutral functional differential inclusions in Banach spaces. Our main aim is to find an effective method to solve the controllability problem of impulsive neutral functional differential inclusions with ...

Second Order Impulsive Neutral Functional Differential Inclusions [PDF]

open access: yesKyungpook mathematical journal, 2008
Abstract. In this paper, we investigate the existence of solutions of second order im-pulsive neutral functional differential inclusions which the nonlinearity F admits convexand non-convex values. Some results under weaker conditions are presented. Our resultsextend previous ones.
