Jiang, Professor, Professor and Doctoral Supervisor of Mathematics Department of Suzhou University, party member. He is currently the president of Suzhou University. Since 1954, Professor Jiang has been engaged in higher education in Beijing Institute of Aeronautics, Peking University and Suzhou University successively, and has rich teaching experience for forty years. Professor Jiang loves the socialist motherland, adheres to the Four Cardinal Principles, is fair in handling affairs, upright in style, high in policy level and strong in leadership. Under his leadership, Suzhou University pays special attention to strengthening the teaching staff and discipline construction, and attaches great importance to the cultivation and improvement of young teachers. He is loyal to the people's education, has a high level of teaching and learning, excellent professional ethics, and has made outstanding achievements in teaching, scientific research and school management. Professor Jiang is an accomplished mathematics educator. He is rigorous in his studies and tireless. Over the past 40 years, a large number of professionals including doctors and masters and many outstanding young scholars have been trained. He pays attention to the comprehensive implementation of the party's educational policy and cares about the healthy growth of students. Every time he goes abroad to work, he takes time to talk with overseas students, publicize the party's line, principles and policies, help them improve their understanding of the party, socialism and reform and opening up policies, help them improve their professional level, and mobilize them to return to China as soon as possible after their studies to serve the motherland. For many years, the professor has been devoted to teaching research. Based on many years' teaching experience, he has compiled two textbooks, Finite Element Method and Its Theoretical Basis and Lectures on Mathematical and Physical Equations, which have been adopted by many universities in China and won the first prize of excellent textbooks of the State Education Commission 1987 and 1992 respectively. Since 1950s, Professor Jiang has been engaged in the research on the theory and application of partial differential equations, especially on the free boundary problem. In the mathematical theory of seepage mechanics and its application in oilfield development, in the mathematical theory of rock stress with weak interlayer, in the study of definite solutions of quasi-linear degenerate elliptic and parabolic equations, and in the theoretical analysis of finite element method, important work has been done to reach the international advanced level. For this reason, Professor Jiang is recognized by the international mathematical community as "a pioneer in studying free boundary issues" and "the most famous expert on free boundary issues in China". │ │ Professor Jiang won the National Natural Science Award twice in 1982 and 199 1, won the Science and Technology Progress Award of the State Education Commission twice, and won many other ministerial and provincial awards. Professor Jiang is currently an academic member of the Institute of Mathematics of China Academy of Sciences, editor-in-chief of Partial Differential Equations magazine, part-time professor in Peking University, East China Normal University and Jiaotong University successively, editorial board member of Journal of Mathematics Northeast Mathematics and Mathematics Research and Review, and was awarded as a national-level young and middle-aged expert with outstanding contributions. Professor Jiang has long been engaged in the teaching and research of partial differential equations. He is an influential expert on partial differential equations at home and abroad. He has published more than 60 papers in China Science, Journal of Mathematics, Science Communication, Partial Differential Equations (USA), Cybernetics and Optimization (USA) and other important magazines at home and abroad. He has profound attainments in elliptic and parabolic equations and their applications. Especially, the result of the existence and uniqueness of the classical solution of the one-dimensional two-phase Stefan problem and the infinite differentiability of the free edge is a breakthrough recognized at home and abroad. At present, it is in the leading position in the world, cited by many monographs and papers at home and abroad, and highly praised by experts at home and abroad. The functional partial differential equation 1978 won the National Science Conference Award, the theory of double-medium seepage 1982 won the third prize of the National Natural Science, and the degenerate elliptic and parabolic equations and the monograph finite element method 1986 won the second prize of the State Education Commission. At the same time, since 1980, he has been invited to give lectures and engage in research work in the United States, Italy, the Federal Republic of Germany and Canada for seven times. 1987 and 1990, he gave a speech at the fifth international conference on free borders and was elected as the host of the "phase change group". Professor Jiang not only made contributions to the country in scientific research, but also made outstanding achievements in teaching. Doctoral supervisor has trained a number of senior talents such as doctoral students and master students for the country, presided over and organized graduate classes of partial differential equations in some universities across the country, and made remarkable achievements in personnel training. Comrade Jiang has been engaged in the teaching and research of partial differential equations for a long time and is an influential expert on partial differential equations at home and abroad. He has published 42 papers in China Science, Mathematical Journal, Scientific Newsletter, Journal of Differential Equations (USA) and other important magazines at home and abroad, and co-published 3 monographs, including Finite Element Method and Its Theoretical Basis, Well Testing Theoretical Basis and Lecture Notes on Mathematical and Physical Equations. He has profound attainments in elliptic and parabolic equations and their applications, especially the existence and uniqueness of the classical solution of one-dimensional two-phase Stefan problem and the infinite differentiability of the free interface. It is recognized as a breakthrough at home and abroad, and is currently in the leading position in the world. It has been cited by many monographs and papers at home and abroad and highly praised by experts at home and abroad. The research results of cooperation with others have won the National Science Conference Award, the third prize of the National Natural Science Award, the Excellent Science and Technology Award of the State Education Commission, and the first prize of the Excellent Textbook of the State Education Commission. At the same time, since the 1980s, he has been invited to give lectures and engage in research in the United States, Italy and the Federal Republic of Germany for six times. 1June, 987, he delivered a speech at the 4th International Conference on Free Borders, and was elected as Comrade Jiang, who not only made important contributions to the country in scientific research, but also made outstanding achievements in teaching. He is a doctoral supervisor, and has trained a number of senior talents such as doctoral students and master students for the country. He has presided over and organized graduate classes of partial differential equations in some universities across the country, and has made remarkable achievements in personnel training.
