王元1930—2021

生平

王元原籍江苏镇江丹徒，1930年4月15日生于浙江兰溪。1952年毕业于浙江大学数学系，师从苏步青教授。因成绩优异，被推荐到中国科学院数学研究所，一年后又被分配到该所数论组师从华罗庚。1980年，当选为中国科学院院士。1986年6月，中国科学技术协会第三次全国代表大会在北京召开，选举产生第三届全国委员会。6月28日，第三届全国委员会第一次会议召开，推举其担任常务委员。

学术贡献

1950年代至1960年代初，他首先将解析数论中的筛法用于哥德巴赫猜想的研究，并证明了命题“3＋4”，1957年又证明了“2＋3”。他与华罗庚开拓了高维数值积分的新研究方向，创造了“华—王方法”。

荣誉

• 陈嘉庚科学奖物质科学奖（1990年）
• 何梁何利基金科学与技术进步奖数学力学奖（1994年）
• 华罗庚数学奖（2000年）

Wang Yuan (Chinese: 王元; pinyin: Wáng Yuán; 29 April 1930 – 14 May 2021) was a Chinese mathematician and writer known for his contributions to the Goldbach conjecture. He was a president of the Chinese Mathematical Society and head of the Institute of Mathematics, Chinese Academy of Sciences.

Life

Wang was born in Lanxi, Zhejiang, China. His father was a magistrate in the local government. Because of the Japanese invasion (the Second Sino-Japanese War), Wang's family had to move away from Zhejiang Province, and finally arrived at the southeast city Kunming in Yunnan in 1938. 1942, Wang's father rose to the position of Chief Secretary of the Academia Sinica. 1946 after the Japanese surrender, his family moved to the capital city, Nanjing. 1946–1949, Wang's father was the Acting Director of the institute. In 1949, Wang separated with his father, who went to Taiwan.

Wang entered Yingshi University (later merged into National Chekiang University, now Zhejiang University) in Hangzhou, and graduated from the Department of Mathematics in 1952. He then earned a position in the Institute of Mathematics, Academia Sinica. Hua Luogeng was his academic adviser and one of his closest collaborators.

In 1966, Wang's career was interrupted by the Cultural Revolution. He was unable to work for more than five years, until 1972. During this time, Wang was harassed and put through interrogation.

In 1978, Wang was back to his professorship, in the Institute of Mathematics at the Chinese Academy of Sciences. In 1980, he was elected to be a member of Chinese Academy of Science. 1988–1992, he was the president of the Chinese Mathematical Society. Wang also worked in the United States for a period of time. He visited the Institute of Advanced Studies and taught at the University of Colorado.

Wang advised Shou-Wu Zhang when he studied at the Chinese Academy of Sciences for his master's degree from 1983 to 1986.

Wang is the father of Chinese American computer scientist James Z. Wang.

Research

Number theory

Wang's research focused on the area of number theory, especially in the Goldbach conjecture, through sieve theory and the Hardy-Littlewood circle method. He obtained a series of important results in the field of number theory.

Numerical integration and statistics

With Hua Luogeng (华罗庚, alternatively Hua Loo-Keng), he developed high-dimensional combinatorial designs for numerical integration on the unit cube. Their work came to the attention of the statistician Kai-Tai Fang, who realized that their results could be used in the design of experiments. In particular, their results could be used to investigate interaction, for example, in factorial experiments and response surface methodology. Collaborating with Fang led to uniform designs, which have been used also in computer simulations.
