Existence of solutions for some Hammerstein type integro-differential inclusions

Electronic Journal of Differential Equations, 2007
In the present work we obtain existence results for Hammerstein type integro-differential inclusions in a finite dimensional space for the cases when the integral multifunction satisfies upper Caratheodory conditions and when it is almost lower ...

A fixed point theorem for upper semicontinuous multifunctions on compact Menger spaces [PDF]

, 1997
In this paper we prove a fixed point theorem for upper semicontinuous multifunction defined on compact Menger spaces. As its application we prove one theorem of Iohvidov-Fans type.

Caratheodory perturbation of a second-order differential inclusion with constraints

Electronic Journal of Differential Equations, 2005
We prove the existence of local solutions for the second-order viability problem $$ ddot{x}(t) in f(t,x(t),dot{x}(t))+F(x(t),dot{x}(t)),quad x(t)in K. $$ Here $K$ is a closed subset of $mathbb{R}^{n}$, $F$ is an upper semicontinuous multifunction with ...

A note on monotone solutions for a nonconvex second-order functional differential inclusion

Le Matematiche, 2011
The existence of monotone solutions for a second-order functional differential inclusion with Carath\'{e}odory perturbation is obtained in the case when the multifunction that define the inclusion is upper semicontinuous compact valued and contained in ...

Existence of solutions for nonconvex functional differential inclusions

Electronic 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 ...

The Method of Generalized Integral Guiding Function in the Periodic Problem of Differential Inclusions

Известия Иркутского государственного университета: Серия "Математика", 2015
In the present paper we consider new methods for solving the periodic problem for a nonlinear system governed by a differential inclusion of the following form: $$x'(t)\in F(t,x(t)).$$ In the first part of the article we assume that the multivalued map ...
