Abstract

In order to study the exact number and states of fixed points in the generalized dynamical system with NAND or NOR local functions over directed rooted trees, structural analysis and classification discussion methods are applied. The exact results of the fixed points in such dynamical systems are obtained. It is proved that the fixed points in such dynamical systems are completely determined by the loops in the rooted trees. This work provides a relevant advance in the knowledge of discrete dynamical systems which constitute mathematical tools to model simulation processes.

Keywords
