Abstract
We prove the existence of mild solutions for the control system governed by fractional delay evolution inclusion in a Banach space X:assuming that the operator A generates a strongly continuous semigroup and the nonlinear part F is a multi-valued function with convex and closed values for which
is weakly upper semicontinuous for a.e.
and
has a
-integrable selection for each
. Moreover, in this setting, we obtain the approximate controllability for such system provided that the corresponding linear control system is approximately controllable. Finally, our results apply, in particular, to the control problem of fractional partial differential inclusion with time delay.
