Optimal Control of Neutral Functional-Differential Inclusions

open access: yesSIAM Journal on Control and Optimization, 2004
Summary: This paper deals with optimal control problems for dynamical systems governed by constrained functional-differential inclusions of neutral type. Such control systems contain time delays not only in state variables but also in velocity variables, which make them essentially more complicated than delay-differential (or differential-difference ...

Novel finite and fixed-time stability theorems for fractional-order impulsive discontinuous systems and their application to multi-agent systems

open access: yesResults in Control and Optimization, 2022
This article studies the finite-time (FNT) and fixed-time (FXT) stability theorems of general fractional-order impulsive discontinuous systems (FOIDSs) through an indefinite Lyapunov functional (LF) approach.

Existence of solutions of functional differential inclusions [PDF]

open access: yesInternational Journal of Stochastic Analysis, 1992
We prove the existence of solutions of a functional differential inclusion. By using the variation of parameters formula we convert the functional differential inclusion into an integral inclusion and prove the existence of a fixed point of the set‐valued mapping with the help of the Kakutani‐Bohnenblust‐Karlin fixed point theorem.

Discrete Approximations of a Controlled Sweeping Process [PDF]

open access: yes, 2014
The paper is devoted to the study of a new class of optimal control problems governed by the classical Moreau sweeping process with the new feature that the polyhe- dral moving set is not fixed while controlled by time-dependent functions.

EXISTENCE OF THE INTEGRAL SOLUTIONS FOR FUNCTIONAL DIFFERENTIAL INCLUSIONS

open access: yesJournal of the Korean Mathematical Society, 2004
The authors prove the existence of integral solutions for a functional differential inclusion of the form \(y'(t)\in Ay(t)+F(t,y_t)\), a.e. for \(t\in [\,0,b\,]\) subjected to the nonlocal condition \(y(t)+(\xi(y_{t_1},\dots,y_{t_p}))(t)=\phi(t)\), for \(t\in [\,-r,0\,]\), where \(A\) is a closed linear operator generating an integrated semigroup in a ...

Effective average action in statistical physics and quantum field theory [PDF]

open access: yes, 2001
An exact renormalization group equation describes the dependence of the free energy on an infrared cutoff for the quantum or thermal fluctuations. It interpolates between the microphysical laws and the complex macroscopic phenomena.

On solutions of differential inclusions in homogeneous spaces of functions

open access: yesJournal of Mathematical Analysis and Applications, 2006
This paper is concerned with the following class of semilinear differential inclusions \[ x'(t)\in Ax(t)+f(t),\;t\in\mathbb R, \] where the multivalued linear operator \(A\in ML(E)\) (\(ML\) is the collection of all closed linear multivalued maps in \(E\)) and \(f\) belong to the homogeneous space \({\mathcal U}(\mathbb R,E)\).

Fabrication of fucoxanthin/2-hydroxypropyl-β-cyclodextrin inclusion complex assisted by ultrasound procedure to enhance aqueous solubility, stability and antitumor effect of fucoxanthin

open access: yesUltrasonics Sonochemistry, 2022
Fucoxanthin (Fx) possesses multiple bioactivities such as antitumor, antioxidant and anti-inflammatory activities, but its application is limited due to the poor water solubility, low bioavailability, and instability to some external harsh conditions. In
