How was Calabi's conjecture broken?
Qiu Chengtong overcame the famous differential geometry puzzle "Calabi conjecture". Qiu Chengtong was originally from Guangdong, China, and later moved to Hong Kong. 1966 entered the Department of Mathematics of the Chinese University of Hong Kong, 197 1 received the doctorate from the University of California, Berkeley, and 1987 received the honorary doctorate from Harvard University. He was a professor of mathematics at Stanford University, Princeton Institute for Advanced Studies and the University of California, San Diego. He has been a professor of mathematics at Harvard University since 1987.

Qiu Chengtong was obsessed with mathematics since he was a child. Through unremitting efforts, he was discovered by a generation of geometry master Chen Shengshen in the third year of college because of his outstanding talent, and became a graduate student at the University of California, Berkeley. Under the personal guidance of Professor Chen Shengshen, Qiu Chengtong, who was only 22 years old, received a doctorate. At the age of 28, Qiu Chengtong became a professor at Stanford University, a world-famous university, and a tenured professor at Princeton Institute of Advanced Studies.

1983, the International Mathematical Congress decided to award the Nobel Prize in Mathematics-Fields Prize to a 34-year-old China mathematician who proved the Calabi conjecture in differential geometry and the positive mass conjecture in general relativity. This talented young man is Qiu Chengtong.

Qiu Chengtong's first important research achievement was to solve the famous differential geometry problem-Calabi conjecture, and he became famous from then on. He applied differential equations to complex variable functions, algebraic geometry and other fields, and achieved extraordinary results. For example, he solved the high-dimensional Minkowski problem and proved the Wan Li conjecture. This series of outstanding work won him the Fields Prize.

Professor Qiu Chengtong is the first Chinese American to win the Fields Prize. He is keen to help develop mathematics in our country. Since 1979, he has given high-quality lectures to Chinese Academy of Sciences for many times. The monograph Differential Geometry published by Science Press is mainly about his research results. He also directly directed the training of more than 0 mathematics doctoral students in China 10, and achieved remarkable results. 1On June 8th, 994, Qiu Chengtong was elected as the first foreign academician of China Academy of Sciences.
