It is shown that CML possesses a yperbolic property displaying a type of spatio-temporal chaos. Through- ut a mathematical background of hyperbolic properties in lattice dynamical ystems which are related to spatio-temporal chaos, a mathematical proof is iven that the CML obtained from the Turing model possesses such hyperbolic roperties. Finally, numerical studies of this finding in varying parameters to resent a variety of chaotic behaviors of this system is performed.Department of Mathematics, Hokkaido University2008-12-08engdepartmental bulletin paperVoRhttps://doi.org/10.14943/84079http://hdl.handle.net/2115/6973910.14943/84079Hokkaido University Preprint Series in Mathematics931120https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/69739/1/pre931.pdfapplication/pdf2.01 MB2008-12-08
