报告摘要：In this report, we will introduce two interconnected works. In 2021, we studied minimal systems with finite sequence entropy. Using some structural properties, we proved that such systems are almost finite-to-one extensions of equicontinuous systems. (Joint work with Huang, Shao, Ye.) Recently, we have taken a step further by demonstrating that for a topological factor map between minimal systems, if the relative sequence entropy of the map is finite, we can also establish a corresponding structure theorem. (Joint work with Tian, Wang.)
