报告摘要: Homogeneous dynamics is a special kind of dynamical systems given by Lie groups. For certain important cases, the systems are ergodic and hence the points with nondense orbits form a set of measure zero. However, the behavior of nondense orbits reflects the complexity of the system and is related to problems in number theory. In this talk, we will discuss some recent progresses of investigations in nondense orbits of homogeneous dynamics, with emphasis on properties of bounded orbits. We will also explain their relations with problems in number-theoretic problems.
