A chemical representation of a chaotic system with a unique stable equilibrium point
(International Federation of Automatic Control, 2018)"In this paper we present a chemical representation of a chaotic system with only one stable equilibrium point. The approach invokes cooperative catalysis and slow-fast reactions, primarily. The obtained chemical based ... -
A class of Chua-like systems with only two saddle-foci of different type
(International Federation of Automatic Control, 2018)"Since the reported Chua’s system, several generalizations of this system have been presented, these approaches include new equilibria in order to obtain three or more scrolls in the attractor. One of these generalizations ... -
A class of Piecewise Linear Systems without equilibria with 3-D grid multiscroll chaotic attractors
