In the present paper, we consider initial-boundary value problems for partial differential equations with time-fractional derivatives which evolve in Q = Ω × (0, T) where Ω is a bounded domain of R d and T > 0. We study the stability of the inverse problem of determining the time-dependent parameter in a source term or a coefficient of zero-th order term from observations of the solution at a point x 0 ∈ Ω for all t ∈ (0, T).
