Firstly, we determine the global existence and uniqueness of the mild solution. Next, under some assumptions on the input data, we discuss continuity with regard to the fractional derivative order for the time. Our key idea is to combine the theories Mittag–Leffler functions and Banach fixed-point theorem. Finally, we present some examples to test the proposed theory.en-USContinuity estimatesDirichlet boundary value problemFractional diffusion equationLiouville derivativeStability of fractional order of time nonlinear fractional diffusion equation with Riemann–Liouville derivativejournal-article
