Abstract
A method for approximating the solution of self-adjoint parabolic equa tions backwards in time is presented. The technique uses the Green's f unction of the parabolic equation to formulate the problem as a first- kind Fredholm integral equation, and then does a regularized least-squ ares solution of the resulting discrete system. Error estimates and ex amples are presented. Direct knowledge of the kernel of the differenti al operator is not required.
