Solution of Inverse Euler-Bernoulli Problem with Integral Overdetermination and Periodic Boundary Conditions

Iranian Journal of Mathematical Sciences and Informatics, 2022
Summary: In this work, we tried to find the inverse coefficient in the Euler problem with over determination conditions. It showed the existence, stability of the solution by iteration method and linearization method was used for this problem in numerical part. Also two examples are presented with figures.

INVERSE PROBLEMS OF RECOVERING THE BOUNDARY DATA WITH INTEGRAL OVERDETERMINATION CONDITIONS

Bulletin of the South Ural State University series "Mathematics. Mechanics. Physics", 2018
In the present article we examine an inverse problem of recovering unknown functions being part of the Dirichlet boundary condition together solving an initial boundary problem for a parabolic second order equation. Such problems on recovering the boundary data arise in various tasks of mathematical physics: control of heat exchange prosesses and ...

Well-posedness of Neumann-type elliptic overdetermined problem with integral condition

AIP Conference Proceedings, 2018
The current paper is devoted to overdetermined elliptic problem with integral condition for derivatives. This overde-termined problem is converted to auxiliary nonlocal boundary value problem (ANBVP) with integral boundary condition. Well-posedness of abstract problem is established.
