Recovery of a fast oscillating source in the heat equation by asymptotic of the solution

Abstract

Four problems about recovery of a high-frequency source in the one-dimension heat equation with homogeneous initial-boundary conditions by some information about partial asymptotic of its solution have solved. It is shown, that the source can be completely recovered from a specific data about incomplete (two-terms) asymptotic of the solution. Before formulation of each problem about recovery of a source, construction and justification of the asymptotic of the solution of original initial-boundary problem is given.
