摘要
We consider the following system coming from a lattice dynamical system stated by Kaneko (Phys Rev Lett, 65:1391-1394, 1990) which is related to the Belusov-Zhabotinskii reaction: where is discrete time index, is lattice side index with system size (i.e., ), is coupling constant, and is the unimodal map on (i.e., , and has unique critical point with and ). In this paper, we prove that for coupling constant , this CML (Coupled Map Lattice) system is distributionally -chaotic for any with , and that its principal measure is not less than . Consequently, the principal measure of this system is not less than for coupling constant and the tent map defined by . So, our results complement the results of Wu and Zhu (J Math Chem, 50:2439-2445, 2012).
