Abstract:
We consider the inverse source problem for a time fractional diffusion equation. The unknown source term is independent of the time variable, and the problem is considered in two dimensions. A bi-orthogonal system of functions consisting of two Riesz bases of the space \(L^2((0,1)\times (0,1))\), obtained from eigenfunctions and associated functions of the spectral problem and its adjoint problem, is used to represent the solution of the inverse problem. Using the properties of the bi-orthogonal system of functions, we show the existence and uniqueness of the solution of the inverse problem and its continuous dependence on the data.
