Extremal Solutions of Functional Differential Inclusions

open access: yesJournal of Mathematical Analysis and Applications, 1993
Let \(X\) be a separable Banach space; \({\mathcal K}\subset X\) be a cone and \(v: [-\tau,a]\to X\) be a solution of a problem \(\dot v(t)\in F(t,v_ t)+{\mathcal K}\), \(t\in [0,a]\); \(v_ 0\geq\varphi\), where \(F\) is a Carathéodory type multifunction with convex closed values satisfying the Ambrosetti type regularity condition. The viability result

On Finite/Fixed-Time Stability Theorems of Discontinuous Differential Equations

open access: yesMathematics, 2022
We investigated the finite/fixed-time stability (FNTS/FXTS) of discontinuous differential equations (DDEs) in this paper. To cope with differential equations that were discontinuous on the right-hand side, we utilized the Filippov solution, which is ...

Analytical investigation of fractional differential inclusion with a nonlocal infinite-point or Riemann–Stieltjes integral boundary conditions [PDF]

open access: yesJournal of Mahani Mathematical Research, 2023
Here, we investigate the existence of solutions for the initial value problem of fractional-order differential inclusion containing a nonlocal infinite-point or Riemann–Stieltjes integral boundary conditions.

Optimal control of the sweeping process over polyhedral controlled sets [PDF]

open access: yes, 2015
The paper addresses a new class of optimal control problems governed by the dissipative and discontinuous differential inclusion of the sweeping/Moreau process while using controls to determine the best shape of moving convex polyhedra in order to ...

Asymptotic analysis of optimal control problems on the semiaxes for Carathéodory differential inclusions with fast oscillating coefficients

open access: yesNonlinear Analysis, 2023
We consider an optimal control problem for a differential inclusion of the Carathéodory type affine with respect to the control with a coercive cost functional on a semiaxis and with fast oscillating time-dependent coefficients.

Lyapunov Functions for Homogeneous Differential Inclusions

open access: yesTransactions of the Society of Instrument and Control Engineers, 2003
Abstract This paper provides a construction method of a smooth homogeneous Lyapunov function associated with a discontinuous homogeneous system, which is locally asymptotically stable. First, we propose a new definition of homogeneous differential inclusion.

The contribution of Alu exons to the human proteome. [PDF]

open access: yes, 2016
BackgroundAlu elements are major contributors to lineage-specific new exons in primate and human genomes. Recent studies indicate that some Alu exons have high transcript inclusion levels or tissue-specific splicing profiles, and may play important ...

Steady heat conduction of material with coated inclusion in the case of imperfect contact

open access: yesMathematical Modelling and Analysis, 2007
We discuss a potential steady heat conduction for composites with the coated cylindrical inclusion under an imperfect contact condition. We rewrite equivalently the considered problem to a conjugation problem for analytic functions which is reduced then ...
