Global stability for the 2-dimensional logistic map

J Dudás - Journal of Difference Equations and Applications, 2019 - Taylor & Francis
For the delayed logistic equation xn+ 1= axn (1− xn− 1) it is well known that the nontrivial
fixed point is locally stable for 1< a≤ 2, and unstable for a> 2. We prove that for 1< a≤ 2 the …
