Abstract We give a relatively short proof of the fact that the solution set of a nonlocal semilinear differential inclusion is dense in the weak solution set of the corresponding convexified system. Moreover, we prove a similar result for the solutio

We show here that the set of the integral solutions of a nonlocal differential inclusion is dense in the set of the solution set of the corresponding relaxed differential inclusion. We further define a notion of limit solution and show that the set o

In this paper we study nonlocal semilinear fractional evolution inclusions involving Riemann-Liouville derivative with right-hand side depending on casual operator. The existence of solutions is proved under compactness type conditions on the multiva

SEVENTH INTERNATIONAL CONFERENCE ON NEW TRENDS IN THE APPLICATIONS OF DIFFERENTIAL EQUATIONS IN SCIENCES (NTADES 2020).
A system of nonlinear Riemann-Liouville fractional differential equations with a constant delay is studied. The initial condition is set up similarly to the case of ordinary derivative. Sufficient conditions for finite time stability are obtained.

In this paper, we study a class of nonlocal functional evolution inclusions in the form of multivalued perturbations of m–dissipative operators. We prove some new existence results in case of dissipative type conditions on the right-hand side. Illu
