| Abstract: | The stability analysis for the solution of the forward-backward problem of the parabolic equation is discussed in the paper. As for countparting forward problem, the stability analysis solution of the forward problem is illuminated. Simultaneity, using the method of the logarithm of the protruding character testify the exponential stability of the inverse problem and get the stability of the estimation.Then numerical simulation experiments are provided,and the results manifests that the numerical solution and the theoretical are well consistent. |
