报告1：相依半重尾索赔离散风险模型有限时破产概率

报告人：苑慧芳

内容介绍：本文将贴现因子看成利率与时间的函数,包含了常利率和变利率两种情况,同时考虑索赔额服从具有独立同分布平稳噪声项的单边线性相依过程,在骋补尘尘补-濒颈办别保险风险条件下,得到一类具有利率和半重尾噪声项的相依索赔离散风险模型有限时破产概率渐近式,并在常利率和变利率情况下进行模拟.

报告2：Neighbor sum distinguishing total coloring of IC-planar graphs

报告人：宋文耀

内容介绍：An IC-plane graph is a topological graph where every edge is crossed at most once and no two crossed edges share a vertex, i.e., two distinct crossings are independent if the end-vertices of the crossed pair of edges are mutually different. If a graph G has a drawing in the plane in which every two crossings are independent, then we call G a plane graph with independent crossings or IC-planar graph for short. In this talk, we give some results on neighbor sum distinguishing total coloring of IC-planar graphs.
