诸位好，本学期首都师范大学第四次数论与代数几何讨论班将于下周举行：
时间：2015年11月4日 周三 上午 10：30--11：30
地点：首都师范大学北二区教学楼513教室（此校区位于西三环紫竹桥南首师大北一区的街对面，走一个过街天桥即到）
报告人：洪久族 博士 (University of North Carolina-Chapel Hill, USA)
题目：Geometric Satake correspondence and saturation problems
摘要：Geometric Satake correspondence provides a uniform way to construct all irreducible representations of reductive groups. It also gives rise to bases of representations and the spaces of their tensor invariants. By recent work of Goncharov-Shen, these bases can be parametrized via tropical geometry. Saturation problems concern multiplicities that appear in decompositions of representations into irreducible components. I will explain how using Knutson-Tao's saturation theorem, the geometric Satake correspondence and parametrization of bases can be applied to get new results about the saturation problem for the spin group Spin(2n+1). This talk is based on the joint work with Linhui Shen.

祝好！
