Local mild solutions and impulsive mild solutions for semilinear Cauchy problems involving lower Scorza-Dragoni multifunctions

open access: yes, 2008
In this note we investigate in Banach spaces the existence of mild solutions for initial problems, also in presence of impulses, governed by semilinear differential inclusions where the non-linear part is a Scorza-Dragoni multifunction. All the results are obtained via a generalization of Artstein-Prikry selection theorem that we obtain in the first ...

Impulsive fractional differential inclusions with infinite delay

open access: yesElectronic Journal of Differential Equations, 2013
In this article, we apply Bohnenblust-Karlin's fixed point theorem to prove the existence of mild solutions for a class of impulsive fractional equations inclusions with infinite delay. An example is given to illustrate the theory.

Neutral stochastic partial functional integro-differential equations driven by G-Brownian motion

open access: yesElectronic Journal of Differential Equations, 2019
In this article, we define the Hilbert-valued stochastic calculus with respect to G-Brownian motion in G-framework. On that basis, we prove the existence and uniqueness of mild solution for a class of neutral stochastic partial functional integro ...

Relaxation in control systems of fractional semilinear evolution equations

open access: yesElectronic Journal of Differential Equations, 2014
We consider a control system described by fractional semilinear evolution equations with a mixed multivalued control constraint whose values are nonconvex closed sets.

Evolution psi-Hilfer fractional differential equations in Banach spaces

open access: yesElectronic Journal of Differential Equations
This article concerns evolution equations involving $\psi$-Hilfer fractional derivative in a Banach space. By using the theory of fractional calculus and $\psi$-Laplace transform, we firstly derive a definition of mild solutions for these equations ...
