Gross and Zagier's Work and New Perspective题目：Gross and Zagier's Work and New Perspective报告人：杨同海 教授（威斯康星大学）地点：致远楼101室时间：2025年6月5日 9:30–10:30Abstract：In 1980s, Gross and Zagier proved a deep and famous formula relating the arithmetic on an elliptic curve to its analysis (L-function). Along the way, they also discovered a beautiful formula of singular moduli. They also raised an algebraicity conjecture o...2025年06月03日
