Periodic solutions for a class of evolution inclusions [PDF]

open access: yesComputers and Mathematics with Applications, 2018
We consider a periodic evolution inclusion defined on an evolution triple of spaces. The inclusion involves also a subdifferential term. We prove existence theorems for both the convex and the nonconvex problem, and we also produce extremal trajectories.

Nonlinear second order evolution inclusions with noncoercive viscosity term [PDF]

open access: yes, 2018
In this paper we deal with a second order nonlinear evolution inclusion, with a nonmonotone, noncoercive viscosity term. Using a parabolic regularization (approximation) of the problem and {\it a priori} bounds that permit passing to the limit, we prove ...

Multi-valued, singular stochastic evolution inclusions

open access: yesJournal de Mathématiques Pures et Appliquées, 2013
We provide an abstract variational existence and uniqueness result for multi-valued, monotone, non-coercive stochastic evolution inclusions in Hilbert spaces with general additive and Wiener multiplicative noise.

Nonlocal evolution inclusions under weak conditions

open access: yesAdvances in Difference Equations, 2018
We study evolution inclusions given by multivalued perturbations of m-dissipative operators with nonlocal initial conditions. We prove the existence of solutions.

Periodic solutions for implicit evolution inclusions [PDF]

open access: yesEvolution Equations & Control Theory, 2019
We consider a nonlinear implicit evolution inclusion driven by a nonlinear, nonmonotone, time-varying set-valued map and defined in the framework of an evolution triple of Hilbert spaces.

Non-degenerate implicit evolution inclusions

open access: yesElectronic Journal of Differential Equations, 2000
We prove the existence of solutions for the implicit evolution inclusion $$ ( B(t) u( t) ) ' + A(t,u(t)) i f(t) $$ under conditions that are easy to verify on the set valued operator $A( t,cdot)$ and that do not imply the operator is monotone.

A class of history-dependent systems of evolution inclusions with applications [PDF]

open access: yesNonlinear Analysis: Real World Applications, 2021
This paper is devoted to studying a system of coupled nonlinear first order history-dependent evolution inclusions in the framework of evolution triples of spaces. The multivalued terms are of the Clarke subgradient or of the convex subdifferential form.

Nonlocal Controllability of Sobolev-Type Conformable Fractional Stochastic Evolution Inclusions with Clarke Subdifferential

open access: yesBulletin of the Malaysian Mathematical Sciences Society, 2022
In this paper, Sobolev-type conformable fractional stochastic evolution inclusions with Clarke subdifferential and nonlocal conditions are studied. By using fractional calculus, stochastic analysis, properties of Clarke subdifferential and nonsmooth ...

Evolution of inclusion populations in Al-killed steel during the steelmaking process

open access: yesJournal of Materials Research and Technology, 2022
The increasing demand for higher steel inclusion cleanliness has motivated control over the formation and evolution of inclusions during the production process.

Fractional Stochastic Evolution Inclusions with Control on the Boundary

open access: yesSymmetry, 2023
Symmetry in systems arises as a result of natural design and provides a pivotal mechanism for crucial system properties. In the field of control theory, scattered research has been carried out concerning the control of group-theoretic symmetric systems ...
