Abstract:
In this article, we consider an inverse problem for a time-fractional
diffusion equation with a linear source in a one-dimensional semi-infinite
domain. Such a problem is obtained from the classical diffusion equation
by replacing the first-order time derivative by the Caputo fractional derivative.
We show that the problem is ill-posed, then apply a regularization method
to solve it based on the solution in the frequency domain.
Convergence estimates are presented under the a priori bound assumptions
for the exact solution. We also provide a numerical example to illustrate
our results.
