Abstract: The source term identification of the time-fractional diffusion-wave equation with Neumann boundary conditions is studied. An improved iterative regularization method is constructed to calculate the regularization solution of the source term. The error estimates between the regularization solution and the exact solution are given under the prior and the posterior regularization parameter choice rules. Numerical examples verify the effectiveness of the iterative regularization method.

Key words: fractional diffusion-wave equation, source term identification, iterative regularization, error estimate
