报告内容简介:
In this talk, we consider the rotation and entropy for the torus maps. The notion of rotational entropy is introduced and it is shown that the rotational entropy is a homotopy invariant. For the random torus maps, we show that the rotation set is a random compact and connected set. We also give a formula of the rotational entropy. This is a joint work with Jiang Weifeng and Lian Zhengxing.
