Su Buqing (September 23, 1902 - March 17, 2003), a native of Pingyang, Wenzhou, Zhejiang Province. He is from Quanzhou City, Fujian Province. He is an academician of the Chinese Academy of Sciences. He is a famous mathematician and educator in China, and the founder of the Chinese Differential Geometry School. He is known as "the brilliant mathematical star in the Eastern country", "the first geometry 2 in the East", and the "king of mathematics".
In 1927, he graduated from the Department of Mathematics of Tohoku Imperial University in Japan. He received his PhD in Science from the school in 1931. He was elected as an academician of the Central Research Institute of in 1948. He was elected as a member of the Chinese Academy of Sciences in 1955. He joined the Communist Party of China in 1959. After 1978, he served as the president of Fudan University, director of the Institute of Mathematics, and honorary president and professor of Fudan University.
Since 1927, he has published more than 160 mathematical papers at home and abroad, and published more than 10 monographs. He founded the internationally recognized Zhejiang University differential geometry school; his research on the geometry and projective curves of "K exhibition space".
Su Buqing is mainly engaged in research on differential geometry and computational geometry, and has achieved outstanding results in the research of affine differential geometry and projective differential geometry, and has achieved outstanding achievements in general spatial differential geometry, high-dimensional space conjugation theory, geometric appearance design, computer-aided geometry design, etc.
In September 1902 (the 28th year of Guangxu in the Qing Dynasty), he was born in a mountain village in Pingyang County, Zhejiang Province. His father made a living by farming. In his childhood, he herded cattle and fed pigs and did farm work such as mowing grass. Although his family was poor, his parents still saved money to support him in school.
In 1911 (the third year of the Xuantong reign of the Qing Dynasty), he went to Pingyang County No. 1 Primary School, more than 100 miles away and became a transfer student.
In 1914 (the third year of the Republic of China), he was admitted to the old four-year Zhejiang Provincial No. 10 Middle School with excellent results.
In July 1919, he just turned 17 years old, and with the support of the middle school principal Mr. Hong, he went to Japan to study. After a month of Japanese tutoring, he participated in the Tokyo Higher Industrial School recruitment in February 1920. With excellent results, he was admitted to the School's Electrical Department.
From 1920 to 1924 (the ninth year of the Republic of China to the thirteenth year of the Republic of China), I studied in the Department of Electrical Engineering of Tokyo Higher Industrial College, Japan.
On September 1, 1923 (the 12th year of the Republic of China), a major earthquake occurred in Tokyo, and escaped from the disaster. All clothes, books and notes were burned. After graduating from Tokyo Higher Industrial School in March of the following year, he applied to the Department of Mathematics, the School of Science, Tohoku Imperial University, a prestigious university in Japan. He ranked first among 90 candidates with full scores in both courses and was admitted as a Chinese student in the Department of Mathematics of Tohoku Imperial University.
In 1927 (the 16th year of the Republic of China), he graduated from the Department of Mathematics of Tohoku Imperial University in Japan.
In early 1928 (the 17th year of the Republic of China), Su Buqing discovered four (third order) algebraic cone surfaces in general surface research. After the paper was published, it had a great response in Japan and the international mathematics community, and was known as the "Su Cone Surface". From then on, Su Buqing taught and conducted research. The research mainly focuses on affine differential geometry, and has published 41 papers in mathematical journals in Japan, the United States and Italy. Some people call him "a brilliant mathematical star rising over the eastern country."
In early 1931 (the 20th year of the Republic of China), I made an appointment with Mr. Chen Jiangong first: after I finished my studies, I went to Zhejiang University together, and spent 20 years to make Zhejiang University Mathematics Department the world's first-class level, to cultivate talents for the country. With deep nostalgia for the motherland and hometown, I finally returned to my hometown after 12 years and taught in the Department of Mathematics of Zhejiang University. The teaching conditions in China are very poor and I can't even pay my salary. With the help of the acting principal, overcome difficulties and adhere to teaching and scientific research. He started a math discussion class with Mr. Chen Jiangong and used strict requirements to cultivate his own students. Even during the Anti-Japanese War, the school moved westward to Guizhou and was forced to hold discussion classes for students in the cave.
In 1933 (the 22nd year of the Republic of China), he was promoted to professor and served as the head of the Department of Mathematics.He and Professor Chen Jiangong designed a modern teaching plan, attaching importance to basic mathematics training, and strict requirements for students. Each course has exercise classes. Students need to go to the blackboard to calculate questions, but they cannot continue if they can't figure it out. It is called " hanging blackboard "
In 1937 (the 26th year of the Republic of China), the Department of Mathematics of Zhejiang University had shown strong strength in cultivating talents and began to recruit graduate students. His earliest student, , Fang Dezhi, has written a research paper. In the second half of the year, when Su Buqing was evading air strikes, he also carried documents and insisted on researching in the air raid shelter. In Meitan , Su Buqing led several of his early students, Xiong Quanzhi , Zhang Sucheng , Bai Zhengguo , etc., to persist in the research on projective differential geometry, and produced a series of important results. Many papers have been published in influential international journals and enjoy a high reputation in the international geometry community. The differential geometry school of Zhejiang University, led by Su Buqing, has begun to form. Zhejiang University moved back to Hangzhou. Su Buqing and Chen Jiangong saw the need to connect the branches of mathematics, implemented the principle of teaching according to their aptitude, and decided to let two outstanding students, Gu Chaohao and Zhang Mingyong, participate in the two discussion classes of "differential geometry" and "function theory", which was also a pioneering move at the time. Zhejiang University also sent several top students to the Institute of Mathematics, the Central Academy of Research Institute, located in Shanghai, and several academically accomplished teachers were selected to study abroad. This is a measure they have made to expand foreign exchanges.
