Existence and controllability for stochastic evolution inclusions of Clarke's subdifferential type [PDF]

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2015
In this paper, we investigate a class of stochastic evolution inclusions of Clarke's subdifferential type in Hilbert spaces. The existence of mild solutions and controllability results are given and proved by using stochastic analysis techniques ...

Trajectory Controllability of Clarke Subdifferential-Type Conformable Fractional Stochastic Differential Inclusions with Non-Instantaneous Impulsive Effects and Deviated Arguments

open access: yesFractal and Fractional, 2023
In this study, the multivalued fixed point theorem, Clarke subdifferential properties, fractional calculus, and stochastic analysis are used to arrive at the system’s mild solution (1). Furthermore, the mean square moment for the aforementioned system (1)

Monotonicity Arguments for Variational–Hemivariational Inequalities in Hilbert Spaces

open access: yesAxioms, 2022
We consider a variational–hemivariational inequality in a real Hilbert space, which depends on two parameters. We prove that the inequality is governed by a maximal monotone operator, then we deduce various existence, uniqueness and equivalence results ...
