A note on Verhulst's logistic equation and related logistic maps

Abstract

We consider the Verhulst logistic equation and a couple of forms of the corresponding logistic maps. For the case of the logistic equation we show that using the general Riccati solution only changes the initial conditions of the equation. Next, we consider two forms of corresponding logistic maps reporting the following results. For the map xn + 1 = rxn(1 − xn) we propose a new way to write the solution for r = −2 which allows better precision of the iterative terms, while for the map xn + 1 − xn = rxn(1 − xn + 1) we show that it behaves identically to the logistic equation from the standpoint of the general Riccati solution, which is also provided herein for any value of the parameter r.
