报告地点:理学院楼四层A401报告厅

报告人简介: 林东奎先生于20156月博士毕业于韩国庆北国立大学数学系基础数学专业。自201512月以来为南开大学数学博士后流动站在站博士后师从郭军义教授20165月获得国家博士后基金的资助。目前的研究兴趣是解析数论在概率金融数学中的应用。已发表学术论文11篇,其中9篇被SCI索引。

报告摘要:The Stirling polynomials are a family of polynomials that generalize important sequences of numbers, such as the Stirling numbers and the Bernoulli numbers, appearing in combinatorics and analysis.

In this talk, the lecturer will give a short and general introduction to the Stirling polynomials, talk about some symmetric identities of three variables and related to the Stirling polynomials under symmetric group , and, by specializing those identities, obtain some interesting symmetric identities for the Stirling polynomials in two variables.
