Abstract

For parabolic equations parametrized by a diffusion coefficient, we consider an inverse problem of finding a source function from a time distributing overdetermining data. We prove that the inverse problem is well-posed in the sense of Hadamard except for a finite set of diffusion parameters. The proof is based on the real analyticity on the parameter and the analytic Fredholm alternative theorem.
