Here we have to linearize around a trajectory, not a point, which we need to solve numerically. The same idea is used in calculating Floquet and Lyapunov exponents. NettetIn fact, there will be two solutions which approach the equilibrium point as , and two more solutions which approach the equilibrium point as .
