| Abstract: | In this paper, the existence of the inverse problem for the following heat conduction problem with a source function under the condition of u(x, T)= h (x) is studied, where q (x) is an unknown function. An ekistence theorem of inverse problem is given by the Galerkin approximation method and the theory of toplogical degree. |
