报告题目：Generalized neck analysis of harmonic maps from surfaces
报告时间：2021年3月4日 周四 14:00-15:00
摘要：In this talk we will study the limit of a sequence of harmonic maps from surfaces with uniformly bounded energy. We define the generalized neck domain as the union of ghost bubbles and necks that are directly connected and give a uniform upper bound of the energy density on the generalized neck domain. As an application, we prove an inequality of the index and nullity of the sequence.
