Chen Jingrun people have loved mathematics since childhood, especially under the influence of some math teachers, and have developed a strong interest in the wonderful and charming number theory. During his stay in Xiamen, after studying hard, he deeply understood the monographs and some important number theory methods of Noguera Doff, a master of mathematics, and wrote his first paper. After being transferred to the Institute of Mathematics of Chinese Academy of Sciences, under the guidance of Yan Shi, the research level has made a leap, and the intelligence has been fully exerted in a good academic environment. He has published more than 50 academic papers and written four books. He has made many important achievements and made indelible contributions in solving many important problems of modern analytic theory, such as the Willing problem, the integer problem on the sphere and the integer problem on the circle, the minimum prime number problem in arithmetic progression, the distribution of almost prime numbers among societies, the constant estimation in the triple prime number theorem, Goldbach conjecture and the twin prime number problem.
Especially in the study of Goldbach's conjecture, Chen Jingrun got the brilliant achievement of (1, 2), that is, he proved that every even number large enough can be expressed as the sum of a prime number and an integer with the number of prime factors less than 2. 1966, Chen Jingrun announced the proof in Science Bulletin (1 2), but only described several lemmas without giving detailed proof, so it was not recognized by the international mathematics community at that time. 1973, he published a detailed proof of (1 2) in China Science, and improved the numerical results published in 1966, which immediately caused a sensation in the international mathematics field, and was recognized as a great contribution to Goldbach's conjecture research and a brilliant culmination of screening theory. His achievements are called "Chen Theorem" by international mathematicians, and have been written into many number theory books in the United States, Britain, France, the Soviet Union, Japan and other countries. Because of the importance of this theorem, people have given at least five simplified proofs for it. Chen Jingrun has always maintained a world record and a leading position in the research field of Goldbach conjecture.
Mr. Zeng has won many awards, such as National Science Conference Award, National Natural Science Award, Heli Fund Award and Mathematics Award. His academic achievements have been recognized at home and abroad. When the International Congress of Mathematicians introduced Pombini's work of winning the Fields Prize in 1974, it especially mentioned that "Chen Theorem" was one of the closely related works. Chen Jingrun was invited by the International Congress of Mathematicians twice and gave a 45-minute lecture at 1978 and 1982 respectively, which was a very high honor. He visited Europe and America in the late 1970s and early 1980s. Since 1978, many doctoral students have been trained.
Chen Jingrun's infatuation and love for mathematics has reached the level of infatuation, and mathematical research is almost his whole life and spiritual sustenance. He is not a genius, but he has superhuman diligence and tenacious perseverance. He devoted himself tirelessly to mathematics research for many years, forgot to eat and sleep, and worked more than 12 hours a day. His achievements were bought with his life. Whether he was treated unfairly during the Cultural Revolution or tortured by love diseases, he never stopped his pursuit and made great contributions to the development of mathematics in China. His deeds and dedication have been widely celebrated throughout the country, and he has become a spiritual force to inspire the people of the whole country to carry out the new Long March after the downfall of the Gang of Four, and has become a legend and a model for a generation of young people.
Chen Jingrun is honest, sincere, humble, easy-going and approachable. Everyone says that he is a really good man. He has low requirements for life and does not compete with the world; However, the goal of scientific struggle is very high, and we must strive for a place for the Chinese nation in the international frontier.
Due to long-term poverty and overwork, Chen Jingrun was in poor health. On 1984, she got Parkinson's disease again. He struggled tenaciously with his illness, persisted in his work, trained graduate students and wrote a lot. The party and the government attach great importance to and care about him. Comrade Xiaoping personally instructed relevant departments to care about Chen Jingrun's health and work. Leaders from the Central Organization Department, the United Front Work Department, the Ministry of Health, the Chinese Academy of Sciences, and Beijing Municipality visited many times to express their condolences and solved some practical problems. Chen Jingrun once lived in 309 Hospital, Beijing Hospital, China-Japan Friendship Hospital, Beijing Third Hospital, xuanwu hospital, Guang 'anmen Hospital and Zhongguancun Hospital. And got good treatment and care. Fujian Provincial Party Committee, Fujian Provincial Government and Fuzhou Municipal Party Committee and Municipal Government invited Chen Jingrun Fujian College of Traditional Chinese Medicine for treatment twice to show their concern and respect for him. Chen Jingrun's wife and daughter have been taken care of by Dr. Kun and other relatives for many years, and all walks of life have also extended a helping hand. He deeply felt the warmth of his family and society and was full of gratitude. His condition once improved and eased, giving people comfort and hope. But suffering from Parkinson's disease and other diseases for a long time, his body is too weak after all. In the middle of this year 1 month, I had a high fever for a long time because of the aggravation of pneumonia. There was cardiac arrest and respiratory arrest, and he woke up after emergency rescue, but it was difficult to control the development of the disease. Later, he was in distress many times. Despite all efforts, he still died of respiratory and circulatory failure at the age of 631March, 199619th13rd. His death is a great loss to the mathematics field in our country.
During the critical period of Chen Jingrun, the leading comrades of the Central Organization Department, the United Front Work Department, the Ministry of Health and the Chinese Academy of Sciences visited the hospital many times. With a highly responsible spirit, Beijing Hospital made every effort to treat patients, and their medical ethics were moving.
On his deathbed, Chen Jingrun seemed to try his best to open his eyes. However, he is too tired. He needs a rest. He didn't realize that he had reached the end of his life. More than a month ago, his condition improved slightly, and he was so happy that he naively sang songs such as "I am a soldier". He is full of affection for comrades, relatives and friends, especially for his beloved wife Yu Kun and his beloved son. He left in a hurry, leaving no last words. But he always said: what conditions are good now, young people should work hard and do research better.
