Chen Jingrun (May 22, 1933 to March 19, 1996), male, Han nationality, born in Fuzhou, Fujian Province, is a famous Chinese mathematician.

Born in Cangshan District, Fuzhou City, Fujian Province on May 22, 1933. He studied in the Department of mathematics of Xiamen University from 1949 to 1953 and was assigned to Beijing No.4 Middle School in September 1953. In February 1955, he was recommended by the president of Xiamen University, Mr. Wang Yanan, and returned to his alma mater, Xiamen University, as a teaching assistant. In October 1957, thanks to the appreciation of Professor Hua Luogeng, Chen Jingrun was transferred to the Institute of mathematics, Chinese Academy of Sciences. The detailed proof of (1 + 2) was published in 1973, which is recognized as a significant contribution to the study of Goldbach conjecture. In March 1981, he was elected member (academician) of the academic department of the Chinese Academy of Sciences. He was a member of the mathematics discipline group of the State Science and Technology Commission and a researcher of the former Institute of mathematics of the Chinese Academy of Sciences. In 1992, he was the chief editor of Acta Mathematica Sinica.

At 1:10 p.m. on March 19, 1996, Chen Jingrun died in Beijing hospital at the age of 63.

On December 18, 2018, the CPC Central Committee and the State Council awarded Comrade Chen Jingrun the title of reform pioneer, the reform pioneer medal, and the model of encouraging young people to climb the scientific summit.

On September 25, 2019, he was selected into the list of "most beautiful fighters".

Life of the characters

Born on may 221933 in Minhou County, Fujian Province (now Lulei village, Chengmen Town, Cangshan District, Fuzhou City).

In February 1948, he was admitted to the spring class of Fuzhou Yinghua high school.

In the summer of 1950, he was admitted to the Department of mathematics and physics of Xiamen University.

From 1949 to 1953, he studied in the Department of mathematics of Xiamen University. After graduating from the University, they will be assigned by the government to teach in Beijing NO.4 middle school.

From 1953 to 1954, he was a teacher in No.4 Middle School of Beijing. Because of his unclear words, he was suspended and returned to his hometown to recuperate.

In 1954, he was transferred back to Xiamen University as a data officer. At the same time, he studied number theory. He also studied the close relationship between combinatorial mathematics and modern economic management, scientific experiments, cutting-edge technology and human life.

In February 1955, recommended by Wang Yanan, the president of Xiamen University at that time, he returned to his alma mater, Xiamen University, as an assistant professor in the Department of mathematics.

In 1956, he published the tower problem, which improved the result of Hua Luogeng's theory of prime numbers.

In September 1957, due to the attention of Professor Hua Luogeng, he was transferred to the Institute of mathematics, Chinese Academy of Sciences as a research intern.

From 1960 to 1962, he was transferred to Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

He was an assistant researcher in 1962.

In 1965, he said that he had proved (1 + 2), which was reviewed by his elder martial brother Wang Yuan and published in the scientific bulletin in June 1966.

In 1966, he published "the table of even number is the sum of a prime number and a product of no more than two prime numbers" (referred to as "1 + 2"), which became a milestone in the study of Goldbach's conjecture.

In 1973, he published the detailed proof of "1 + 2" in Chinese science and improved the numerical results announced in 1966, which immediately caused a sensation in the International Mathematical circles. It is recognized as a significant contribution to the study of Goldbach conjecture and a brilliant summit of sieve theory. His achievement is called "Chen's theorem" by the International Mathematical circles and has been written in many number theory books of the United States, Britain, France, the Soviet Union and Japan. This work also enabled him, Wang Yuan and pan Chengdong to win the first prize of China Natural Science Award in 1978.

In 1974, Premier Zhou, who was seriously ill, personally recommended him as a deputy to the Fourth National People's Congress and was elected a member of the Standing Committee of the National People's Congress.

In January 1975, he was elected a deputy to the Fourth National People's Congress, and later a deputy to the fifth and Sixth National People's Congress.

He was promoted to a research fellow in 1977.

In 1979, he finished his paper "the minimum prime in arithmetic progression", which promoted the minimum prime from 80 to 16, and was highly praised by the international mathematical community.

In 1979, he was invited by Princeton Institute of higher learning to give lectures and visit, which was widely concerned by foreign colleagues.

In 1980, he was elected member of the physics and Mathematics Department of the Chinese Academy of Sciences. (academician)

In March 1981, he was elected member of the academic department of the Chinese Academy of Sciences. (academician)

In 1988, he was designated as a first-class researcher.

He was the chief editor of Acta Mathematica Sinica in 1992 and won the first Hua Luogeng prize for mathematics.

At 1:10 p.m. on March 19, 1996, Chen Jingrun died in Beijing hospital at the age of 63. His last contribution to the cause of science was to donate his body for hospital dissection.

Main achievements

Achievements in scientific research

He is mainly engaged in the research of analytic number theory, and has made international leading achievements in the research of Goldbach conjecture. In the 1950s, we made important improvements on Gauss circle, sphere, tarry problem and warlin problem. Since the 1960s, we have made a deep study on the sieve method and its related important problems. In May 1966, we proved the proposition "1 + 2", which greatly promoted the proof of Goldbach's conjecture, which has not been solved for more than 200 years. This result is internationally known as "Chen's theorem", and then he improved it.

In 1957, Chen Jingrun was transferred to the Research Institute of the Chinese Academy of Sciences. As a new starting point, he studied harder. After more than 10 years of calculation, in May 1966, he published his paper "table even number is the sum of a prime number and a product of no more than two prime numbers". The publication of this paper is highly valued and praised by the world's mathematical circles and famous mathematicians. British mathematician haberstein and German mathematician Richter wrote Chen Jingrun's paper into mathematics book, which is called "Chen's theorem".

Award winning record

Anecdotes of characters

Goldbach's conjecture, a reportage that has caused a sensation in China, has made Chen Jingrun, a mathematical wizard, a household name overnight. On March 2, 1973, he published his famous paper "the large even number is expressed as the sum of a prime number and a product of no more than two prime numbers" (i.e. "1 + 2"), which greatly promoted the proof of Goldbach's conjecture which has not been solved for hundreds of years and caused a sensation, and was named "Chen's theorem" in the world. He has superhuman diligence and tenacious perseverance. Over the years, he has devoted himself tirelessly to mathematics research, forgetting to eat and sleep, and working more than 12 hours a day. When suffering from illness, he never stopped his pursuit and made great contributions to the development of mathematics. His deeds and dedication are widely praised all over the country, becoming a legendary figure and learning model in the minds of generations of young people.

The archives of Sanming No.1 Middle School (formerly Sanyuan county junior high school) in Sanming City, Fujian Province, are collected. After years, they seem to tell the vicissitudes of history. Looking at Volume 3 of the first catalogue, we can see that although some of the handwriting is faded, we can see the footprints left by the famous mathematician Chen Jingrun in Sanming: in February 1945, he was promoted to Sanyuan county junior high school, and there were 18 students in the class. The length of schooling was set at three years. In January 1947, Chen Jingrun left Sanyuan county junior high school with his father before he finished grade 2 and grade 3 The county returned to Fuzhou.

Little stories and legends about Chen Jingrun after high school are widely spread, but his study process and life experience in Sanming are hardly mentioned. Looking at his life materials, there is only one simple sentence: "from 1938 to 1948, he studied in Sany primary school, Sanyuan County primary school, Sanyuan county junior high school, Sanyi middle school and Yinghua middle school in Fuzhou City."

In 1977, Chen Jingrun was hospitalized in 309 hospital because of illness. He met you Kun, who had just been sent to the hospital by Wuhan military region for further study. In the past, Chen Jingrun didn't even touch the edge of a woman's name, and didn't even say a word. This time, when Chen Jingrun, nearly half a century old, saw you Kun, his eyes lit up, and he cordially said hello to you Kun. Later, Youkun was sent to Chen Jingrun's ward as a doctor on duty. In this way, there are more opportunities for contact. Chen Jingrun is very happy every time you appear. One day, Chen Jingrun asked Youkun with concern where he lived? Do you have a boyfriend or a family? You Kun had no defense, so she said frankly, "no, no, it's still early." Later, you Kun was also very concerned about the Chinese mathematician, and they fell in love with each other. Finally, one day, you Kun asked the mathematicians around him: "you are a great mathematician, and many people worship you. Why did you choose me?" Facing his beloved girl, Chen Jingrun flushed with anxiety. He didn't want young people's vows. After a long time, Chen Jingrun said: "I've thought about it. If you don't agree, I won't get married in my life." It is this sentence that makes you Kun no longer hesitate. She calmly accepts Chen Jingrun's feelings and helps each other for 16 years.

They got married with the help of the organization. From then on, Chen Jingrun, a mathematician known as "fool" and "weirdo", had a warm home.

Character evaluation

Chen Jingrun is the sum of the world's intellectual limit in the 250 years of challenging analytic number theory. If there were a thousand Chen Jingrun in China, it would be great. (comments by zhonghua.com and Deng Xiaoping)

Every work Mr. Chen Jingrun does seems to be walking on the top of the Himalayas. It is dangerous, but once successful, it will certainly affect the world. (on Andre Wye, French mathematician)

Chen Jingrun has a passion for mathematics and has amazing perseverance to complete his mathematics research, which is his most valuable personality and quality. (Changchun daily)
