The phase space analysis has been used to probe the accelerated expansion of the Universe when ω ( q ) dark energy interacts with cold dark matter. Non-gravitational interactions Q = 3 H b q ρ de and Q = 3 H b q ρ dm considered in this work are one of the first models of sign changing interactions t...
