Academician Wu Wenjun, the winner of the first National Science and Technology Award and a master of mathematics, died in Beijing on May 7th at the age of 98. According to the obituary published by the Institute of Mathematics and System Science of China Academy of Sciences, Wu Wenjun is one of the most internationally influential mathematicians in China, and his work has a far-reaching impact on the research of mathematics and computer science. Academician Ma Zhiming, former chairman of the chinese mathematical society, told the reporter of China Youth Daily and Zhongqing Online today that Mr. Wu Wenjun is a master of mathematics, and his status can be seen from the award of the first national highest science and technology award. "He is a mathematician we love very much. His influence on mathematicians of our generation is profound. " Ma Zhiming was very surprised when he received a phone call from a reporter this morning. He heard the news that Mr. Wu was seriously ill some time ago, but he hasn't heard the bad news yet. The reporter learned from Mr. Wu Wenjun's funeral office that Mr. Wu was hospitalized for cerebral hemorrhage because he accidentally fell down at home. After being admitted to the hospital in early April, he recovered well for a time, but deteriorated again in May. On April 1 1, when Bai Chunli, President of Chinese Academy of Sciences, visited him in the hospital, his condition was stable. His doctor smiled and said, "Grandpa is very cute and cooperative." According to Ma Zhiming, Wu Wenjun studied mathematics until his later years. His contribution to mathematics includes not only the well-known field of mathematical mechanization, but also his research on ancient mathematics in China. For a long time, he has devoted a lot of efforts to building China into a powerful mathematical country, and has done a lot of work for the organizational construction and discipline development of China's mathematics community. According to the obituary of Chinese Academy of Sciences, Wu Wenjun won the first National Science and Technology Award, Shaw Prize in Mathematics, Outstanding Achievement Award in Automatic Reasoning, and the highest international automatic reasoning award. The demonstrative class and embedded class he introduced are called "Wu demonstrative class" and "Wu demonstrative embedded class", and the relationship between demonstrative classes he derived is called "Wu formula". His work is one of the major breakthroughs in topology around 1950' s, and it has become a classic achievement with far-reaching influence. 1In the late 1970s, he initiated a brand-new field of mathematical mechanization and put forward the "Wu method" to prove geometric theorems by computer, which is considered as a pioneering work in the field of automatic reasoning. In 2002, the International Congress of Mathematicians was held in China for the first time. Wu Wenjun was the president of the conference, and Ma Zhiming, then president of chinese mathematical society, was the chairman of the organizing committee. Ma Zhiming said that Mr. Wu always hoped that China would become a powerful country in mathematics. "He said that we have done a lot of work well, but we have been following foreigners. He hopes that we have China people's own research direction and open up our own research direction. " This is also the deepest impression that Wu Wenjun left on Ma Zhiming. "He often said that when we do research, we should have our own direction in China and don't always follow others." He said that the mechanization of mathematics initiated by Mr. Wu proved to be China people's own direction and thought. On the occasion of Wu Wenjun's 90th birthday, Ma Zhiming wrote a congratulatory letter on behalf of chinese mathematical society. In his congratulatory letter, he quoted Wu Wenjun's views on different occasions: "We have done a good job, but the field was initiated by others and the problems were raised by others. We have done very good work, some of which have solved the unsolved problems of others, and we have done admirable work in other people's fields. But I don't think that's enough. We should create our own fields and ask our own questions. In the long run, we must innovate, have our own path, have our own direction, and have our own thoughts. We cannot completely follow others. " Ma Zhiming said that Mr. Wu paid special attention to the younger generation of mathematicians. He is very approachable and friendly to everyone. He is an "old urchin" and is open-minded about everything. In recent years, Wu Wenjun seldom goes out. On one occasion, Ma Zhiming saw him take a taxi at the gate of the community. Wu Wenjun, an octogenarian, took a taxi to a nearby bookstore. He likes studying there very much. Despite its high status, Wu Wenjun is not treated as a "special car". Academician Yuan Yaxiang, a mathematician, mentioned in an interview with China Youth Daily and Zhongqing Online that Academician Wu Wenjun doesn't have a car. Wu Wenjun 19 12 was born in Shanghai in May 2009, 1940 graduated from Shanghai Jiaotong University, and 1946 worked in the Institute of Mathematics of Academia Sinica. From 65438 to 0947, he went to study at the University of Strasbourg, France, and received a national doctorate from France from 65438 to 0949. Later, he worked as a researcher at the French National Science Center. After the founding of New China, Wu Wenjun returned to China on 195 1. In his life, his teacher and international mathematician Chen Shengshen had a great influence on him. Chen Shengshen brought him into the field of topology research, which is one of his most important research fields. In 2004, Chen Sheng died of illness at Nankai University. Wu Wenjun, who went to pay his respects at that time, told the reporter of China Youth Daily and Zhongqing Online: "Chen Shengshen is my guide, which determines my life's work and scientific path. If I hadn't met him at that time, I would probably have accomplished nothing in mathematics. " When the Shaw Prize, known as the "Oriental Nobel Prize", was established, Chen Shengshen won the first Shaw Prize in mathematics, and Wu Wenjun was then the chairman of the jury of the Mathematical Science Award. Later, Wu Wenjun himself won this honor. In his later years, Wu Wenjun was always known as an "old urchin". Five years ago, when he was interviewed by China Youth Daily and Zhongqing Online, he said that he knew little about "specific knowledge". Now "mainly reading novels", "all kinds of novels, good-looking novels". He commented that "Japanese detective stories are very interesting". In his view, Japanese detective novels reflect a profound social background, unlike the British Sherlock Holmes series, which attract people with some strange stories. The master of mathematics also said at that time that he could "do something else" in mathematics-"I think I can do something else. I dare not say how much I can do. "
