| contents | In this paper, we investigate the direct and linear inverse problems of identifying time-dependent and time-independent source terms in a time-fractional diffusion-wave equation, using measured data at an interior point of the time interval. We first establish the existence, uniqueness, and regularity of the solution to the direct problem by employing the spectral method. Then, based on the properties of the direct problem, we study two inverse problems: one involving the recovery of a time-independent source term, and the other concerning the identification of a time-dependent coefficient function in the source term. |
