| Abstract: | It is shown that maps of topological chain ergodicity is invariable under property of topological conjugate.Topological chain ergodicities of f k and f1×f2×…×fn are studied,and an equivalent condition of topological chain ergodicitys of fk and f for any integer k and an equivalent condition of topological chain ergodicities of fi,i=1,2,…,and f1×f2×…×fn are given.In addition,it is shown that if(X,f) is topological chain ergodicity,then its lift map(X～,d～) is topological chain ergodicity. |
