摘要

We provide a class of triangular maps of the square, (x, y) -> (f(x), g(x)(y)) of type 2(infinity), i.e., such that the periods of periodic points are the powers of 2, which has a minimal set supporting positive topological entropy. This improves the famous example by S. Kolyada from 1992 and contributes to the solution of an old problem by A.N. Sharkovsky.
