Inverse Sturm–Liouville Problem with Spectral Parameter in the Boundary Conditions

open access: yesMathematics, 2023
In this paper, for the first time, we study the inverse Sturm–Liouville problem with polynomials of the spectral parameter in the first boundary condition and with entire analytic functions in the second one.

Explicit power laws in analytic continuation problems via reproducing kernel Hilbert spaces [PDF]

open access: yesInverse Problems, 2019
The need for analytic continuation arises frequently in the context of inverse problems. Notwithstanding the uniqueness theorems, such problems are notoriously ill-posed without additional regularizing constraints.

A source inverse problem for the pseudo–parabolic equation with the fractional Sturm–Liouville operator

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
A class of inverse problems for restoring the right-hand side of the pseudo-parabolic equation with one fractional Sturm–Liouville operator is considered.

The Regional Enlarged Observability for Hilfer Fractional Differential Equations

open access: yesAxioms, 2023
In this paper, we investigate the concept of regional enlarged observability (ReEnOb) for fractional differential equations (FDEs) with the Hilfer derivative. To proceed this, we develop an approach based on the Hilbert uniqueness method (HUM). We mainly

Stability and Uniqueness for Piecewise Smooth Solutions to a Nonlocal Scalar Conservation Law with Applications to Burgers-Hilbert Equation

open access: yesSIAM Journal on Mathematical Analysis, 2019
In this paper, we show uniqueness and stability for the piecewise-smooth solutions to the Burgers--Hilbert equation constructed in Bressan and Zhang [Commun. Math. Sci., 15(1):165--184, 2017].

Regional Controllability and Minimum Energy Control of Delayed Caputo Fractional-Order Linear Systems

open access: yesMathematics, 2022
We study the regional controllability problem for delayed fractional control systems through the use of the standard Caputo derivative. First, we recall several fundamental results and introduce the family of fractional-order systems under consideration.

Averaged Control Problems Governed by a Semilinear Distributed Systems

open access: yesJournal of Mathematics, 2023
In this work, we consider the regional averaged controllability (RAC) problem governed by a class of semilinear hyperbolic systems. We start by giving the definitions of the exact and approximate RAC systems.

The Clifford Hilbert transform and Riemann-Hilbert problems associated to the Dirac operator in Lebesgue spaces

open access: yesApplied Mathematics and Computation, 2020
In this paper, we establish some properties of the Hilbert transform in Clifford analysis setting, and mainly show the weak type (1,1) inequality for the Clifford Hilbert transform in Euclidean space R m (m ≥ 3) using the Clifford algebra and analysis ...

Controllability for a Wave Equation with Moving Boundary

open access: yesJournal of Applied Mathematics, 2014
We investigate the controllability for a one-dimensional wave equation in domains with moving boundary. This model characterizes small vibrations of a stretched elastic string when one of the two endpoints varies. When the speed of the moving endpoint is
