Overdetermined Hardy Inequalities

open access: yesJournal of Mathematical Analysis and Applications, 1997
The aim of the paper is to find necessary and sufficient conditions on the weights \(w\) and \(w_0\) for the validity of the higher-order Hardy inequality \[ \Biggl(\int^1_0| u|^qw_0\Biggr)^{1/q}\leq C\Biggl(\int^1_0| u^{(k+ 1)}|^p w\Biggr)^{1/p} \] on the class of all solutions of certain overdetermined boundary value problems.

Retrieval of Timewise Coefficients in the Heat Equation from Nonlocal Overdetermination Conditions

open access: yesIraqi Journal of Science, 2022
     This paper investigates the simultaneous recovery for two time-dependent coefficients for heat equation under Neumann boundary condition. This problem is considered under extra conditions of nonlocal type.

Well-posedness of an inverse problem for two- and three-dimensional convective Brinkman-Forchheimer equations with the final overdetermination [PDF]

open access: yesInverse Problems and Imaging, 2021
In this article, we study an inverse problem for the following convective Brinkman-Forchheimer (CBF) equations: \begin{document}$ \begin{align*} \boldsymbol{u}_t-\mu \Delta\boldsymbol{u}+(\boldsymbol{u}\cdot\nabla)\boldsymbol{u}+\alpha\boldsymbol{u ...

Numerical solution to Bitsadze-Samarskii type elliptic overdetermined multipoint NBVP

open access: yesBoundary Value Problems, 2017
This paper is devoted to a Bitsadze-Samarskii type overdetermined multipoint nonlocal boundary value problem (NBVP). This inverse problem is reduced to an auxiliary multipoint NBVP.

Existence and Uniqueness of the Solution for an Inverse Problem of a Fractional Diffusion Equation with Integral Condition

open access: yesJournal of Function Spaces, 2022
The solvability of the fractional partial differential equation with integral overdetermination condition for an inverse problem is investigated in this paper. We analyze the direct problem solution by using the “energy inequality” method.

AN INVERSE PROBLEM OF RECOVERING THE RIGHT HAND SIDE OF 1D PSEUDOPARABOLIC EQUATION

open access: yesВестник КазНУ. Серия математика, механика, информатика, 2021
Inverse problems of finding the right-hand side of a partial differential equations arise when an external source is unknown or impossible to measurement, for example, the source is in a high-temperature environment or underground.

Solving the problem of overdetermination of quasisymmetric equilibrium solutions by near-axis expansions. I. Generalized force balance [PDF]

open access: yes, 2020
It is well known that the process of construction of quasisymmetric magnetic fields in magnetostatic equilibrium with isotropic pressure suffers from the problem of overdetermination.

THE PROBLEM OF NATURAL DIVINE CAUSATION AND THE BENEFITS OF PARTIAL CAUSATION: A RESPONSE TO SKOGHOLT

open access: yesZygon, 2020
In this article, I defend my previous argument that natural divine causation suffers under the problem of causal overdetermination and that it cannot serve as a line of demarcation between theistic evolution (TE) and intelligent design (ID).
