报告摘要:In this talk, we consider the rotation theory for a random dynamical system on the torus. Here the system is generated by random composition of a collection continuous maps, each of which is homotopic to the identity. The notions of rotation set and rotational entropy are introduced. It is shown that the rotation set is a random compact and connected set, and the rotational entropy is zero under certain conditions.
