Determination of the source/sink term in a heat equation
Ping Wang & Kewang Zheng
Abstract:
In this work, we consider the problem of determining an unknown
parameter in a heat equation with ill-posed nature.
Applying Tikhonov regularization, we obtain
a stable approximation to the unknown parameter from over-specified data.
We also present numerical computations that verify the accuracy of our
approximation.
