His collaborator Professor Wu Gongfu is an expert in ordered Banach space theory. At one time, he and Huang Youchuan studied for a doctorate in Swan Sea. Since then, they have launched a research competition to encourage each other. Everyone is very excited and happy. Huang Youchuan 1973 conducted research on nuclear space and L-nuclear space at Yale University. The monograph [8, 9, 10] marks his academic research achievements in the mid-1970s. Among them, the monograph was highly appraised. In commenting on this book. Ji 'an-carlo rota pointed out: "Although some (mathematics) projects have been declared to have been completed many times, they can still be redeveloped in some aspects. Ordered topological vector space because this book has a similar experience. " Advanced Mathematics (2) 2008.
1979, Huang Youchuan was awarded the Doctor of Science degree by the University of Wales, which is one of the highest honors in British academic circles. Doctor of Philosophy (Ph.D) is the highest academic qualification that can be obtained in the British academic system. If the doctoral graduates have outstanding academic achievements in a few years, they will pass the unanimous examination by three experts of our bank. The university where he graduated will award him the title of doctor of science. In its congratulatory message to Huang Youchuan, United College pointed out: "Doctor of Science is a lofty honor of the scientific community. The winners are all people who have made great contributions to science. " (Joint Power, Volume I,No. 13 (1970)) Huang Youchuan also regarded this as the greatest honor in his life. He often encourages his two sons and daughters and students with his personal successful experience: "whatever you can achieve through personal struggle (such as exam results, degrees, works, etc.). ), individuals.
In the same year, Huang Youchuan's "Schwartz Space, Nuclear Space and Tensor Product" written for springer Publishing House was published in Volume 726. This monograph follows bourbaki's concept of spatial classification, and refers to the quasi-Schwartz operator developed by D. Randtke and the skill of satisfying some semi-norm classes. The topology or bounded structure of various special and important locally convex spaces is related to various corresponding operator subclasses or semi-norm classes. Therefore, for semi-norm classes with special properties, the spatial structure of them is studied by using the method of operator theory. The evaluation of this book by the mathematical community is very different. The book review published in the Journal of the London Mathematical Society gave a high evaluation of this book. However, book reviews and "mathematical reviews" in the journal of the American Mathematical Society.
In fact, Huang Youchuan has developed μ-topology mainly introduced by I.Stephani through many different examples of locally convex topological spaces and ordered locally real topological spaces, without using the ideal tool of operators (Pietsch's representative work "Operator Ideal" was not published at that time). After 1980, Huang Youchuan actively promoted cultural exchange activities between Chinese mainland and Hong Kong and Taiwan.
During the period of 1985, he gave two lectures at Sun Yat-sen University in Guangzhou, the topics were "cone absolutely summable operator and ordered tensor product" and "operator ideal and space ideal", which were well received by academic circles. Since then, he often visited his alma mater and was also well received. 1990, he was hired as a visiting professor by Zhongshan University in Guangzhou. 19980.9899898999 16
During 1989, Huang Youchuan was invited to give a series of academic lectures in China Academy of Sciences, Peking University, Tsinghua University, Hefei University of Technology and Shanghai Fudan University. Many mathematicians are his good friends, such as Yang Le, Gu Chaohao, Hu, Li Bingren, Lin Wei and Zhou. 1990, he should be Chen. Huang Youchuan taught as a national "Mathematics Graduate Education Center" for one month. The lecturers are all excellent graduate students from mainland universities. The purpose is to consolidate the foundation and broaden our horizons. When he was the head of the Department of Mathematics at the Chinese University of Hong Kong, he often went to the Mainland to recruit potential students for further study at the Chinese University, so as to cultivate talents for the mathematics field in China.
With the development of academic exchanges between Chinese mainland, Hong Kong and Taiwan, Huang Youchuan gave lectures in Taiwan Province many times and met many outstanding mathematicians. August+0980-July+19865438, Huang Youchuan was a visiting research professor at the Institute of Mathematics, Academia Sinica, Taipei. At that time, I was invited by Professor Chen Mingbo. Huang Youchuan is a person who loves to make friends, and people in Taiwan Province Province also love to make friends. They talk about academics. Huang Youchuan proposed to hold a lecture workshop once a week in the Institute of Mathematics to learn new knowledge. The host accepted this suggestion. The workshop was a great success, and Huang Youchuan made many good friends with mathematicians in Taiwan Province Province. Huang Youchuan was invited as the keynote speaker). At the "Mathematics Annual Meeting" in Taiwan Province Province 19438+098 1 and 1986.
Universities in Taiwan Province Province are divided into two systems: national universities and private universities. Academia Sinica is an independent research institution, except for Academia Sinica (1980, 198 1, 1988, 1992). Huang Youchuan studied in Taiwan Province Provincial University (198 1), national chengchi university (198 1), National Tsinghua University (1979, 198 1) and other universities. 1990, 199 1, 1992), National Central University (1988), National national cheng kung university (1988) and National Sun Yat-sen University (65438). His lectures are never repeated. Every time he gives a speech in Chinese mainland or Taiwan Province, he always brings four or five lectures for people to choose from. Moreover, he has prepared different versions of any topic, which can be taught for one to four hours.
As the saying goes, "Knowing heroes is more important than heroes", Huang Youchuan met many mathematicians with broad minds and extraordinary knowledge in Taiwan Province Province. Among them, Professor Shi Maoxiang, who is currently the head of the Department of Mathematics at Chung Yuan Christian University, is a famous expert in fixed point theory. He met Huang Youchuan in a speech in Huang Youchuan. Shi said: "Huang Youchuan is a very tolerant person and a very good friend." Because of similar interests, he invited Huang Youchuan to visit Zhongyuan University several times. They soon became good friends. By 1987, Huang Youchuan's research enthusiasm was burning again. His monograph Introduction to Topological Vector Space, written for Marcel Dacker Publishing House, was published in 1992. This is a pure biography of Huang You, in which the idea of "walking on two legs" is elaborated in great detail and plays a great role. Therefore, Shi Maoxiang specially wrote a chapter "Fixed Point Theory". His other monograph, Functional Analysis and Operator Theory, has been published. He has written nearly 50 papers and monographs, and he has also published in many international mathematics magazines (such as "Lecture Notes on Mathematics" published by Springer-Verlag and "Mathematical Analysis and Its Application" published by London Mathematics magazine. ). He is also a freelance editor of Marcel Dacker Publishing House. He is also often invited to give a special report at international mathematics conferences and serve as the group moderator. He traveled to the mainland all the year round, engaged in mathematical exchanges between Hong Kong and Taiwan, and devoted a lot of efforts to the development of mathematics in China.
199 1 1, The Chinese University of Hong Kong has finally been promoted to Professor Huang Youchuan!
Just as his career was booming, Huang Youchuan was diagnosed with metaphase lung cancer in August. 1992. After partial pneumonectomy and electrotherapy, his fierce illness was slightly relieved. Regrettably, Huang Youchuan's research activities had to be postponed again. Huang Youchuan was a brave soldier until he got sick. Today, he is still teaching doctoral students. He still often goes to the Mathematics Department of the Chinese University to read books, and he is still thinking about mathematics problems. He may continue to enjoy music and match various audio devices. With his healthy recovery, we believe that Huang Youchuan's mathematics career will show a more brilliant page.
Finally, this article ends with Professor Fan's evaluation of Huang Youchuan. In a letter to Professor Shi Maoxiang, Fan said: "You said that he (Huang Youchuan) is a very dedicated mathematician, and he is sincere and sincere. I believe all his friends feel the same way. He works very hard, and he is really a masterpiece. I admire his professionalism very much. "
Friends and righteous teachers discuss and calculate, and rivers converge every day.
Counting the seas with Qian Fan is endless.
