Abstract

A great impetus to study differential inclusions came from the development of Control Theory, i.e. of dynamical systems
$${\text{x'(t) = f}}\left( {{\text{t,x}}\left( t \right){\text{,u}}\left( t \right)} \right){\text{, x(0) = }}{{\text{x}}_0}$$
(*)
“controlled” by parameters u(t) (the “controls”). Indeed, if we introduce the set-valued map
$$F(t,x)\dot = {\left\{ {f\left( {t,x,u} \right)} \right\}_{u \in U}}$$
then solutions to the differential equations (*) are solutions to the “differential inclusion”
$$x'\left( t \right) \in F\left( {t,x\left( t \right)} \right),{\mkern 1mu} x\left( 0 \right) = {x_0}$$
(**)
in which the controls do not appear explicitely.
