First, some theorems have been established from standard fixed point theorems in a proper Banach space to guarantee the existence and uniqueness of positive solution. Moreover, we discuss the Hyers-Ulam stability and parameter perturbation analysis, which examines the stability of solutions in the presence of small changes in the equation main parameters, that is, the derivative order η, the integral order β of the boundary condition, the boundary parameter ξ , and the boundary value τ. As an application, we present a concrete example to demonstrate the accuracy and usefulness of the proposed work. By using numerical simulation, we obtain the figure of unique solution and change trend figure of the unique solution with small disturbances to occur in different kinds of parameters.}, type={Article}, title={Existence, uniqueness and parameter perturbation analysis results of a fractional integro-differential boundary problem}, URL={http://www.czasopisma.pan.pl/Content/127643/PDF/BPASTS_2023_71_4_3445.pdf}, doi={10.24425/bpasts.2023.145938}, keywords={existence and uniqueness, stability analysis, parameter perturbation, fractional differential equation, integro-differential boundary condition}, }
