It is well known that there exists a regular branched covering map from T 2 onto ¯ C i the ramification indices are (2 ;2;2; 2), (2;4;4), (2;3;6) and (3;3;3). In this paper we construct (count- ably many) chaotic homeomorphisms induced by hyperbolic toral automorphism and regular branched covering map corresponding to the ramification indices (2;2;2;2). And we also gave an example which shows that the above construction of a chaotic map is not true in general if the ramification indices is (2;4;4) and also show that there are no chaotic homeomorphisms induced by hyperbolic toral automorphism and regular branched covering map corresponding to the ramification indices (2;3;6) and (3;3;3).
