报告题目： Classification of weighted dual graphs associated to the minimal good resolutions of normal surface singularities

报告人： 左怀青 （清华大学数学科学系）

摘要：Let (V, p )be a normal surface singularity. Let $\pi (M, A ) \rightarrow (V, p )$ be a minimal good resolution of V. The weighted dual graphs associated to A completely describes the topology and differentiable structure of the embedding of A in M. I will present our recent progress on the classification of weighted dual graphs associated to the minimal good resolutions of normal surface singularities. Joint work with Stephen Yau and Qiwei Zhu.
