摘要
In this work, we study the autonomous dynamical system of different F(R) models in the formalism of holographic dark energy using the generalized Nojiri-Odintsov cut-off. We explicitly give the expression of the fixed points as functions of the infrared cut-off for vacuum F(R) gravity in flat and non-flat FRW background and for F(R) coupling axion dark matter. Each fixed point component can be taken as a condition on the cut-off and on the expression of F(R), leading to physically interesting constraints on these functions.
