Analysis:

Chen Shengshen (China Roman word: Shiing-shen Chern,19 10 2004 128 October-3 February 200412) is a Chinese American mathematician. Academician of National Academy of Sciences of China Academy of Sciences, foreign academician of French Academy of Sciences, Italian National Academy of Sciences, Royal Society of England and China Academy of Sciences.

19 1 1 was born in xiushui county, Jiaxing, Zhejiang. 1922 graduated from Xiuzhou Middle School and came to Tianjin. 1923 entered Rotary Middle School (now Tianjin Railway No.1 Middle School). Graduated from 1926, entered the Department of Mathematics of Nankai University, and graduated from 1930 with a bachelor's degree. In the same year, he entered Tsinghua University as a teaching assistant and studied for graduate students. He studied projective differential geometry under Sun Guangyuan, a pioneer of differential geometry in China, and graduated from 1934 with a master's degree. He is the first mathematics graduate student trained by China himself. In the same year, he won a scholarship from China Cultural Education Foundation (one said it was funded by Tsinghua) and went to study in Hamburg University. He studied under the famous geometer Blasce, 65438-0936, and obtained a doctor of science degree. When I graduated, I still had a scholarship left, so I went to Paris, France to study differential geometry with E. Cartan.

1937, Chen Shengshen is Professor Tsinghua University; Later, because of War of Resistance against Japanese Aggression, he moved to Kunming, Yunnan, and taught differential geometry in The National SouthWest Associated University, which was composed of Peking University, Tsinghua University and Nankai University.

1943, at the invitation of American mathematician O. Van Buren, he went to work in Princeton Institute for Advanced Studies. In the next two years, he completed the most important work in his life: he proved the high-dimensional Gauss-Bond formula, constructed the Chen class widely used today, and laid the foundation for global differential geometry.

1946 After the victory of the Anti-Japanese War, he returned to Shanghai and presided over the work of the Institute of Mathematics of Academia Sinica. In the following two or three years, he trained a group of young topologists. At the beginning of 1949, academia sinica moved to Taiwan Province province, and Chen Shengshen moved his family to the United States at the invitation of Oppenheimer, president of Princeton Institute of Advanced Studies. /kloc-in the summer of 0/949, he took over the professorship of E.P.Lane of the University of Chicago; E.P.Lane was Chen Shengshen's mentor when Sun Guangyuan was studying in the United States. It has made an important contribution to the revival of differential geometry in America. From 65438 to 0960, Chen Shengshen was employed as a professor at the University of California, Berkeley, until his retirement. 196 1 was elected as an academician of the American Academy of Sciences. 1963- 1964, vice chairman of the American mathematical society. An important contribution of Chen Shengshen in his later years was the establishment of the National Institute of Mathematics in 198 1 University of California, Berkeley. He was the first director.

1984 retired, and Chen Shengshen was successively employed as honorary professor of Peking University and Nankai University. From 65438 to 0985, he was hired by the Ministry of Education of China as the director of the Institute of Mathematics of Nankai University. In the same year, Nankai University awarded him an honorary doctorate.

Since 1986, chinese mathematical society has established and undertaken the "Chen Shengshen Mathematics Award".

Chen Shengshen died in Tianjin on February 3, 2004 19: 00 Beijing time.

Wu Wenjun, Liao, Zheng and other famous scholars all studied under them.

achievement

Combining differential geometry and topological methods, Chen Shengshen has successively completed two epoch-making important works: one is the generalized Gauss-Bonner formula of Riemannian manifold, and the other is the indicator theory of Hermite manifold. Some concepts, methods and tools he introduced have gone far beyond the scope of differential geometry and topology and become an important part of modern mathematics. Chen Shengshen's other important mathematical works include:

Tight dipping and tight dipping began with him and R. Leshev for more than 30 years, and their achievements have been compiled into monographs.

One of the famous results of complex geometry of value distribution of complex variable function is Chen-Porter theorem.

Hypersurface matching Yan Zhida of integral geometric motion formula.

Chen of real hypersurfaces on complex manifolds? Mo Ze's theory is the basic work of the theory of multiple complex variables.

Minimal surface and harmonic mapping.

Chen-Simmons differential formula is the basic tool of quantum mechanical anomalies.

honour

Chen Shengshen has won many scientific honors.

196 1 year, after physicist Wu Jianxiong, Chen Shengshen was elected as the second Chinese-American member of the National Academy of Sciences, which is the highest honorary position in the American scientific community.

1970 won the Shoffnett Award of American Mathematical Association.

1976 was awarded the National Science Medal by President Ford, which is the highest award in the fields of science, mathematics and engineering in the United States; Chen Shengshen and Wu Jianxiong were the first China scientists to receive this honor.

1983, Steele Prize for "All Achievements" of American Mathematical Society.

1984 was awarded the Wolff Prize in mathematics by Israeli President Hoso, which is the highest prize in the field of mathematics in the world; Chen Shengshen is the first mathematician in China and the second scientist in China who won the Wolff Prize.

In addition, he was awarded the Chau-ve Award (1970) and the Steele Award (1983) by the American Mathematical Society. He also won the German Humboldt Prize and the Russian Lobachevsky Prize in Mathematics. In addition, in 2004, he won the first Shaw Prize in Mathematical Science. 165438+1October 2, the asteroid 1998CS2 was named "Chen Shengshen Star" after discussion and approval by the Committee on Small Celestial Bodies of the International Astronomical Union.

Chen Shengshen was invited to speak at the International Congress of Mathematicians three times: 1950 in Boston, Cambridge, USA, 1958 in Edinburgh, Scotland, and 1970 in Nice, France. 1950 and 1970 are both one-hour reports, which are the highest-level academic speeches of the International Congress of Mathematicians.

Chen Shengshen served as the vice chairman of the American Mathematical Society. He is also a foreign academician of French, Italian, China and other countries. He is also the founder of the Third World Academy of Sciences, a foreign member of the Royal Society, a correspondent of the Brazilian Academy of Sciences and an honorary member of the Indian Mathematical Society. He was awarded honorary doctorate by Swiss Federal Institute of Technology, Berlin University of Technology, Hong Kong University of Science and Technology and many other famous universities.

Chen Shengshen is regarded as the greatest differential geometer in the 20th century. Chen Shengshen, Hua and Feng Kang are considered as three China mathematicians with world-class achievements and international influence. He is also the mentor of Fields Medal winner Qiu Chengtong at the University of California, Berkeley.
