内容摘要：In this talk, we introduce the application of Kazhdan-Lusztig maps in the study of Poisson geometry and total positivity. First, we introduce its definition and its Poisson geometric interpretations. Then, we use Kazhdan-Lusztig maps to construct a class of toric charts on the flag variety and show that their positive equivalent class coincide with the Lusztig total positive structure. Last, we point out the connections of above two parts. This is a joint work with Lu Jiang-Hua.
