Webknow how trajectories behave near the equilibrium point, e.g. whether they move toward or away from the equilibrium point, it should therefore be good enough to keep just this term.1 Then we have δ˙x =J δx; where J is the Jacobian evaluated at the equilibrium point. The matrix J is a constant, so this is just a linear differential equation. WebFixed point theory is one of the outstanding fields of fractional differential equations; see [22,23,24,25,26] and references therein for more information.
