Attractors of asymptotically periodic multivalued dynamical systems governed by time-dependent subdifferentials

open access: yesElectronic Journal of Differential Equations, 2004
We study a nonlinear evolution equation associated with time-dependent subdifferential in a separable Hilbert space. In particular, we consider an asymptotically periodic system, which means that time-dependent terms converge to time-periodic terms as ...

Existence Results for Nonconvex Nonautonomous Differential Inclusions in Hilbert Spaces

open access: yesMathematics
We establish a solvability criterion for nonautonomous time-evolution inclusions governed by the right-hand side without the convexity assumption. In this study, we examine the problem x˙(t)∈F(t,x(t))a.e.onI0:=[0,T0], for some T0>0, where F has a closed ...

On Fr\'{e}chet Subdifferential of Supremum for Arbitrary Family of Continuous Functions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
The paper focuses on the Fr\'{e}chet subdifferential of the pointwise supremum of the family of functions taken over arbitrary index sets. The all functions in the corresponding family are defined on a Fr\'{e}chet smooth space; this class of Banach ...

Automatic feedback control for one class of contact piezoelectric problems

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï, 2014
In this paper we investigate the dynamics of solutions of the second order evolution inclusion with discontinuous interaction function which can be represented as the difference of subdifferentials.

Existence Results and Gap Functions for Nonsmooth Weak Vector Variational-Hemivariational Inequality Problems on Hadamard Manifolds

open access: yesMathematics
In this paper, we consider a class of nonsmooth weak vector variational-hemivariational inequality problems (abbreviated as, WVVHVIP) in the framework of Hadamard manifolds.
