报告摘要 Abstract: 

In this talk we will discuss the problem on the density of polynomial orbits for a given totally minimal system. First we state the background of the problem, and then we briefly describe how to solve it under a stronger condition, namely under the weak mixing assumption. Finally, we explain the ideas how to solve it for some polynomials under the total minimality assumption. Some open questions will be stated at the end of the talk.
