An inverse coefficient problem for a quasilinear parabolic equation with periodic boundary and integral overdetermination condition
Authors:
Publisher and Date:(Wiley-Blackwell, 2015)In this paper the inverse problem of finding the time-dependent coefficient of heat capacity together with the solution periodic boundary and integral overdetermination conditions is considered. Under some natural regularity and consistency conditions on the input data the existence uniqueness and continuous dependence upon the data of the solution are shown. Some considerations on the numerical solution for this inverse problem are presented with an example. Copyright (c) 2014 John Wiley & Sons Ltd.

Determination of a diffusion coefficient in a quasilinear parabolic equation
Authors:
Publisher and Date:(De Gruyter Open Ltd, 2017)This paper investigates the inverse problem of finding the time-dependent diffusion coefficient in a quasilinear parabolic equation with the nonlocal boundary and integral overdetermination conditions. Under some natural regularity and consistency conditions on the input data the existence uniqueness and continuously dependence upon the data of the solution are shown. Finally some numerical experiments are presented.

Determination of an Unknown Heat Source from Integral Overdetermination Condition
Authors:
Publisher and Date:(Springer International Publishing, 2018)In this research we consider a coefficient problem of an inverse problem of a quasilinear parabolic equation with periodic boundary and integral over determination conditions. We prove the existence uniqueness and continuously dependence upon the data of the solution by iteration method. Also we consider numerical solution for this inverse problem using linearization and finite difference method is proved.

Two-dimensional inverse quasilinear parabolic problem with periodic boundary condition
Authors:
Publisher and Date:(Taylor & Francis Ltd, 2019)In this study we consider a coefficient problem of a quasi-linear two-dimensional parabolic inverse problem with periodic boundary and integral over determination conditions. We prove the existence uniqueness and continuously dependence upon the data of the solution by iteration method. Also we consider numerical solution for this inverse problem by using linearization and the implicit finite-difference scheme.
