Reconstruction of the right-hand side of the elliptical equation from observation data obtained at the boundary. (English) Zbl 1199.65373
Author’s abstract: We consider the classical inverse problem in potential theory in which it is required to determine the unknown right-hand side of the elliptic equation in the case in which additional data are set on the boundary of the calculation domain. To simplify the consideration, we restrict ourselves to the two-dimensional Poisson equation.
