报告摘要:The theory of total positivity for an arbitrary reductive group was developed by Lusztig in 1994. It has many beautiful algebraic, combinatorial and geometric properties, and has had significant impacts on several active research directions. In this talk, I will survey some recent important results in this area. After that, I will discuss the regular properties of unipotent elements in total positivity and confirm a conjecture by Lusztig. This is based on a joint work with Haiyu Chen.
