Inverse problem of determining the absorption coefficient in the multidimensional heat equation with unlimited minor coefficients

Abstract

The inverse problem of reconstructing the absorption coefficient (from L2) in the multidi-mensional heat equation under an additional integral observation condition is studied. It is assumed that the minor coefficients belong to the Lebesgue space. For the solution to the inverse problem, sufficient conditions for existence, uniqueness, and stability to perturbations of input data are established. These conditions are formulated in the form of easy-to-check inequalities.
