Approximation of inverse source problem for time fractional pseudo-parabolic equation in $L^p$ [PDF]

Mathematics and Computational Sciences, 2023
In this work, we focus on the final value problem of an inverse problem for the pseudo-parabolic equation. This study aims to provide a regularization method for this equation, once the measurement data are obtained at the final time in $L^{r}(0,\pi ...

Regularization of a final value problem for a linear and nonlinear biharmonic equation with observed data in $ L^{q} $ space

AIMS Mathematics, 2022
In this work, we focus on the final value problem of an inverse problem for both linear and nonlinear biharmonic equations. The aim of this study is to provide a regularized method for the bi-harmonic equation, once the observed data are obtained at a ...

Mixed inverse problem for a Benney–Luke type integro-differential equation with two redefinition functions and parameters

Қарағанды университетінің хабаршысы. Математика сериясы, 2023
In this paper, we consider a linear Benney–Luke type partial integro-differential equation of higher order with degenerate kernel and two redefinition functions given at the endpoint of the segment and two parameters.

A modified quasi-boundary value method for a class of abstract parabolic ill-posed problems

Boundary Value Problems, 2006
We study a final value problem for first-order abstract differential equation with positive self-adjoint unbounded operator coefficient. This problem is ill-posed.

On an initial and final value problem for fractional nonclassical diffusion equations of Kirchhoff type

Discrete & Continuous Dynamical Systems - B, 2020
We study for nonlinear Kirchhoff's model of pseudo parabolic type by considering its two different problems. \begin{document}$ \bullet $\end{document} For initial value problem, we obtain the results on the existence and regularity of solutions. Moreover,

A quasi-boundary value regularization method for the spherically symmetric backward heat conduction problem

Open Mathematics, 2023
In this article, we investigate a spherically symmetric backward heat conduction problem, starting from the final temperature. This problem is severely ill posed: the solution (if it exists) does not depend continuously on the final data.
