Theory for Local Activity of Three-Port CNN With Four State Variables

The Local activity theory of the Cellular Nonlinear Network(CNN) has provided a powerful tool for studying the emergence and change of the dynamic behaviors of complex systems consisting of homogeneous media. The local activity principle is explainedand a set of theorems are set up for testing the local activity of three-port CNN and studying the life phenomena related to the growth of cellular tissues under cellmediated cytolysis.
