Inverse moving source problems for parabolic equations

Abstract

This paper is concerned with the inverse moving source problems for parabolic equations. Given the temporal function, we prove the uniqueness of the nonlinear inverse problem of determining the orbit function by final data measured in a bounded domain. On the other hand, given the orbit function we also show that the profile function can be uniquely determined by final data measured in a bounded domain away from the domain enclosing the moving orbit. The proofs adopt the Fourier approach and results from complex analysis.
