19 1 1 years later, Feng Zuxun served as the head of the Department of Mathematics in Peking University for many times, and made important contributions to the dissemination of modern mathematics knowledge in China.
Before and after the Revolution of 1911, few people in China studied modern mathematics and made some achievements. Now (1909), Zheng (19 10) and (19 13) have obtained bachelor's degrees from Cornell University. After the Revolution of 1911, Shi Jing University Hall was renamed Peking University. 19 12 10, Feng Zuxun became a science professor in this school. By 19 13, Peking University had opened a math class (equivalent to the current "department"), and Feng Zuxun was the main professor of the department. Since then, He, He, Hu and others have made outstanding contributions to the construction of the Department of Mathematics in Peking University (before 1934, Feng Zuxun was the head of the department for many times), initially explored a school-running model of the Department of Mathematics in modern universities in China, and gradually improved the curriculum. 19 17 The main courses of Peking University Mathematics (19 19, which was officially changed into a department by Peking University, are: analytic geometry (three-dimensional), calculus, physics and physics experiments, chemistry and chemistry experiments, function theory, differential equations and harmonic functions, modern algebra, and so on. By the end of the 20th century, astronomy, higher plane curve, differential geometry, integral equation, set theory, variational method, infinite series, elliptic function and elliptic module function were added one after another. Feng Zuxun is good at analyzing themes. The courses taught by Feng Zuxun in the annual courses from 1924 to 1925 include: set theory, integral equation theory and differential equation theory, infinite series theory, variational method, elliptic function theory and elliptic module function theory. Feng Zuxun has high requirements for lectures, and the selected textbooks are very deep. For example, in the differential equation course of the third grade, the original "Mathematical and Physical Equations" co-authored by D. Hilbert and R. Courant is selected as the teaching material. In the class of set theory, he introduced the set theory published by F. Hausdorf in 19 14. His teaching method advocates the German school, speaks deeply and arranges many exercises, but does not strictly examine whether students do it or not. Besides being busy with teaching, Feng Zuxun has also done some academic research. 19 19 19 The first issue of Peking University Monthly has his article "Studying the Properties of Cubic Equation Roots with Images". 1930 The National Natural Science Quarterly of Peking University published his "On the Mother of Module Substitution" in Volume 2, Issue 1. In addition, Feng Zuxun also wrote papers such as "A New Proof of Cauchy Integral Formula".
Feng Zuxun has been actively supporting students' academic activities. 19 18 Peking university students set up a "mathematical society" and published a "mathematical magazine"; Beijing Normal University (hereinafter referred to as Beijing Normal University, 1923 renamed Beijing Normal University) has also set up a similar organization to publish periodicals. Feng Zuxun once serialized his long work Theory of Differential Equations in Journal of Mathematical Physics of Beijing Normal University, which played a positive role in promoting the study and research of differential equations in early China. He also made many popular academic reports to stimulate students' thirst for knowledge.
Feng Zuxun devoted himself to promoting post-school education, and the story of cultivating Fu was passed down as a much-told story. Feng Zuxun was the head of the Department of Mathematics of Beijing Normal University for many years. Fu Yu 19 17 entered the school to study mathematics, showing great talent. After graduation, he went to the middle school affiliated to Beijing Normal University to teach. 192 1 year, in order to concentrate on the work of Peking University, Feng Zuxun wanted to train Fu to preside over the work of the Department of Mathematics in Beijing Normal University, so he was transferred back to the Department of Mathematics, and one year later Fu was promoted to a lecturer. Later, Feng Zuxun recommended him to take a part-time job at Peking University, which eventually prompted Fu Zai 1928 to become a professor of mathematics at Beijing Normal University, and later became a famous mathematics educator in China.
By 1930s, modern mathematics in China had made great progress. The Department of Mathematics in Peking University has also made great progress. Jiang Zehan 193 1 After teaching at Peking University, he helped Feng Zuxun to promote teaching reform and international academic exchanges. The Department of Mathematics invited German E. Sperner and American W. F. Osgood as professors, and also invited German W. blaschke (B 1aschke) and American G.D .. During this period, the Department of Mathematics of Peking University also trained some excellent students. Later, due to Fan? Wang, Zhang, etc. In this situation, the conditions for establishing mathematicians' own national academic organizations are becoming more and more mature. 1929, chinese mathematical society was founded by Feng Zuxun and Zhang (a physicist). Its founding declaration states: "... I know that to promote scientific progress in China, I must advocate basic science. Therefore, the chinese mathematical society was initiated by colleagues in the field of mathematical physics of North and South University. They are engaged in the dissemination and discussion of new theories while contacting mathematical scientists from various countries. " Since then, the voice of establishing a separate mathematical society has become louder and louder. Initiated and prepared by Hu Dunfu, Zhu and Gu Cheng in Shanghai, chinese mathematical society was finally established in Shanghai 1935, and Feng Zuxun was elected as one of the nine directors. Feng Zuxun also served as the head of the Department of Mathematics of Northeastern University with Zhang Xueliang as the principal.
During the War of Resistance against Japanese Aggression period, Peking University moved south to Kunming and formed Southwest Associated University with Tsinghua University and Nankai University. Feng Zuxun stayed in Beijing for health reasons. He taught in Peking University, which was located in Peiping during the Japanese occupation, and helped to transfer the student status files of the Department of Mathematics of Peking University to Kunming. 1940( 194 1? ) Feng Zuxun died in 1920. After War of Resistance against Japanese Aggression's victory, Peking University returned to Beijing, and Feng Zuxun was reburied by the school on 1947. The tomb is located in Futian Cemetery, Badachu. The tombstone is inscribed by Hu Shizhi, and the inscription is "The Tomb of Mr. Feng Hanshu". Fan? Feng Zuxun's tomb was rebuilt on 1993, and the inscription was written by Su.
