LLE calculation of sine map: (a) original equations and (b) identified model. The -axis is the number of iterates and the -axis is the log of the lower bound error.
(a) Simulation of (11), with results for and and the same initial condition; that is, . LLE calculated is the inclination of the curve given by 1.133. |
(b) Simulation of (13), with results for and and the same initial condition; that is, . LLE calculated is the inclination of the curve given by 1.114. |
