题目:A global Torelli theorem for certain Calabi-Yau threefolds

报告人:许金兴  副教授(中国科学技术大学)

摘要:The cyclic triple cover of the three dimensional complex projective space branched along six hyperplanes in general position is a Calabi-Yau threefold. By varying the hyperplane arrangements, we get a complete family of Calabi-Yau threefolds. I will show the global Torelli theorem holds for this Calabi-Yau family. The main ingredients of the proof are Deligne-Mostow's results on branched cyclic covers of the projective line and a monodromy group computation. This is a joint work with Mao Sheng.
