报告摘要：

In this talk, we consider the combination of the rotation theory and the entropy theory for the torus maps. The rotational entropies, including topological version and measure-theoretic version, are introduced. It is shown that the topological rotational entropy is a homotopy invariant, and there is a variational principle relating these two versions of rotational entropies. The rotational entropy is also considered for the random torus maps. This is a joint work with Weifeng Jiang and Zhengxing Lian.
