The existence of spatial chaos in the sense of Li and Yorke is proved using the Marotto theorem. These results extend the corresponding results in the 1D Logistic system [Formula: see text] where n<jats:sub>0<\/jats:sub>is a fixed integer. These results also improve some existing results of the 2D coupled map lattice (CML) model [Formula: see text] where \u03b5 &gt; 0 is the coupling constant.<\/jats:p>","DOI":"10.1142\/s0218127403007126","type":"journal-article","created":{"date-parts":[[2003,6,25]],"date-time":"2003-06-25T00:53:09Z","timestamp":1056502389000},"page":"1163-1181","source":"Crossref","is-referenced-by-count":20,"title":["ON SPATIAL LYAPUNOV EXPONENTS AND SPATIAL CHAOS"],"prefix":"10.1142","volume":"13","author":[{"given":"SHU TANG","family":"LIU","sequence":"first","affiliation":[{"name":"Institute of Systems Science, College of Automation Science and Engineering, South China University of Technology, Guangzhou, 510641, P.R.
