1in the autumn of 932, Fan joined the Department of Mathematics in Peking University. He wanted to study engineering, but because his uncle Feng Zuxun is the head of the Department of Mathematics at Peking University, and because Peking University doesn't take English exams, he decided to take the road of mathematics. Fan is good at learning mathematics. In the second grade, German mathematician E. Spener came to China to teach "Modern Algebra" in Peking University. The textbooks used are two books, Analytic Geometry and Algebra and Vorlesungen uberMatrizen, co-authored by O. Schreier and Spener. After listening to the lectures, Fan translated them into Analytic Geometry and Algebra in the summer vacation, and Feng Zuxun prefaced them and recommended them to the Commercial Press. 1935, the first edition of this book was published as one of the university series. The seventh edition was published in Taiwan Province Province 1960. In college, Fan also translated Landau's Ideals and Algebra, and co-authored Number Theory with Sun Shuben, which was published by the Commercial Press.
1936 After graduating from Peking University, Fan stayed in school to teach. 1938 In the second half of the year, France returned to the Sino-French Education Foundation established in boxer indemnity to recruit one person in mathematics, one in chemistry and one in biology to study in France. Fan is an admitted student in the Department of Mathematics. 1939 starts for Paris. He planned to study algebra, but before he left, two professors, Cheng (Peking University) and Jiang Shuomin (Nankai University), advised him to learn from Mr. Fréchet, pointing out that "the analysis is similar to algebra". Fan is grateful for this suggestion for life. Indeed, as a pioneer of functional analysis, Fréchet developed a set of abstract analytical structures, which was unique in France, which advocated "hard analysis" such as functional theory at that time. When Fan arrived in Paris, he asked khaddam Ade, who had visited China, to write a letter of introduction. They gradually got to know each other and became Fan's mentor.
194 1 year, Fan took "Several Basic Concepts of General Analysis" as his dissertation, and obtained a national doctorate in France. At that time, the Second World War was going on, and Fan had the honor of becoming a researcher at the French National Center for Scientific Research and engaged in mathematical research at the Poincare Institute of Mathematics. Life in wartime was tense and miserable, but the research work continued to achieve results. By the end of the 1945 war, Fan had published more than 20 papers. The book Introduction to Topological Combination Oils, co-authored by him and Fréchet, was also published in 1946, and later published in English and Spanish.
After World War II, Fan moved to the United States for development. From 1945 to 1947, he is a member of the Princeton Institute for Advanced Studies. At that time, world-famous mathematicians gathered in Princeton, including H. Weyl and J. von Neumann, who had come to the United States before the war. Fan's later work was deeply influenced by them and made greater progress in academics.
1947, Fan went to the University of Notre Dame to teach, from assistant professor and associate professor to professor. 1960 taught at Wayne State University in Detroit for one year, and then transferred to Northwestern University near Chicago. Until 1965, he was hired as a professor of mathematics at the University of California, Santa Barbara.
1964 Taipei academia sinica elected Fan as an academician. 1978 ——19841745. He served as the director of the Institute of Mathematics for two consecutive years. He is also a visiting professor at the University of Texas (Austin), the University of Hamburg, the University of Paris IX and the University of Perugia in Italy. From 1960, he served as the editorial board of Mathematical Analysis and its Application for 32 years. He is also an outstanding editor of Linear Algebra and Its Applications, and was hired as the editorial board of Set-valued Analysis in the Netherlands and Topological Methods in Nonlinear Analysis in Poland in 1993.
1In the summer of 985, Fan officially retired. The mathematical community held a grand academic activity for him, and many mathematicians from all over the world came to participate. The University of California, Santa Barbara, announced the establishment of Ky Fan Assistant Professor. The proceedings of this academic conference on Fan's honorary retirement are entitled "Proceedings of Academic Conference in Memory of Fan Qifang". It contains a catalogue of all the papers written by Fan up to that time.
After retiring, Fan continued to be a magazine editor, and his works are still published. During the period of 1989, he was invited to visit the Chinese University of Hong Kong and served as an excellent visiting scholar in the United College of the university. 1990 In May, the University of Paris IX awarded Fan an honorary doctorate. 1990, he attended a conference on matrix theory and was invited to give a speech after the banquet. 1992 in may, he was invited to visit Poland. 1993 went to Tokyo to attend the conference on nonlinear analysis and convex analysis, and was one of the four academic members of the conference.
After Fan left the mainland from 1947, he had no chance to return to his hometown for a long time. 198 1, preparing to travel to the mainland, which was temporarily cancelled due to surgery. Nankai University held a conference on fixed point theory in 1988, but it was also unable to attend for health reasons. 1989 In May, Fan returned to Beijing at the invitation of Beijing Normal University after more than 50 years' absence. After giving lectures for two weeks, he went to Peking University, Institute of Mathematics of Chinese Academy of Sciences, Wuhan University, Zhejiang University and Hangzhou University to give lectures. During his visit, he was hired as honorary professor of Peking University and Beijing Normal University. Fan donated all his math books and magazines collected for more than 40 years to his alma mater, Peking University, except a few for his own use. 1In May, 1993, Fan returned to China to give lectures on the occasion of the International Symposium on Function Theory held in Hangzhou University to commemorate Professor Chen's birthday100th anniversary.
Professor Ky Fan died at his home in Santa Barbara, USA on March 22, 20 10, at the age of 95.
The death of Mr. Wang shocked the scientific community in the United States and even the world. The American Mathematical Society (AMS), the most authoritative and influential mathematical academic organization in the world, published his life and the news of his death on its website, and successively published special articles to commemorate his great contribution to mathematics. On March 24th, the University of California, Santa Barbara (UCSB), who had taught teachers and students in Qifan for 20 years, specially lowered the flag at half mast for Qifan ... chinese mathematical society and Ky Fan's alma mater, Peking University, also held a grand commemorative event for Mr. Wang. The seventh international conference on nonlinear and convex analysis will be held in Japan on 20 10, with the theme of commemorating Ky Fan. Subsequently, the professional journal Nonlinear and Convex Analysis will publish a special commemorative issue.
