Although exact solutions to the recurrence relation are only available in a small number of cases, a closed-form upper bound on the logistic map is known when 0 ≤ r ≤ 1. There are two aspects of the behavior of the logistic map that should be captured by an upper bound in this regime: the asymptotic geometric decay with constant r, and the fast initial decay when x0 is close to 1, driven by the (1 − xn) term in the recurrence relation. The following bound captures both of these effects: WebDec 21, 2024 · This is the Lyapunov exponent as a function of r for the logistic map ( x n + 1 = f ( x n) = r ( x n − x n 2) ) The big dips are centered around points where f ′ ( x) = 0 for some x in the trajectory used to calculate the exponent … WebJul 1, 2024 · It is confirmed numerically that the fixed point in the logistic map is stable exactly within the interval of parameters where there are no real asymptotically points, and when the asymptotically period two point appears, this point is stable and the fixed point becomes unstable.

WebOn the cobweb plot, a stable fixed point corresponds to an inward spiral, while an unstable fixed point is an outward one. It follows from the definition of a fixed point that these … WebApr 16, 2024 · This map has many periodic points, even with large period. The period-one fixed points − 1, 2 are both repelling fixed points (indices 2 > 1 and 4 > 1, respectively). Thus, fixed-point iterations will not converge towards these values unless the starting value x 0 is exactly equal to − 1 or 2.
