题目:BPS invariants from topological strings

报告人:朱盛茂 (浙江大学)

地点: 21幢第三会议室

时间:1月9日(周三),下午3:00-4:00

摘要:Based on string theory, BPS invariants are integral invariants related to Calabi-Yau manifolds. In this talk, we  will introduce the backgrounds of BPS invariants first. Then we present our recent results on two types of open string BPS invariants:  Ooguri-Vafa invariants and Labastida-Marino-Ooguri-Vafa invariants. We prove the integrality of these invariants for some special Calabi-Yau manifolds. We will also show the relations among the Ooguri-Vafa invariants, quiver varieties and Ramanujan-Rogers identities.
