Editing Chinese mathematics (section)

== People's Republic of China ==
In 1949, at the beginning of the founding of the People's Republic of China, the government paid great attention to the cause of science although the country was in a predicament of lack of funds. The Chinese Academy of Sciences was established in November 1949. The Institute of Mathematics was formally established in July 1952. Then, the Chinese Mathematical Society and its founding journals restored and added other special journals. In the 18 years after 1949, the number of published papers accounted for more than three times the total number of articles before 1949. Many of them not only filled the gaps in China's past, but also reached the world's advanced level.{{sfn|Kong|2015}}

During the chaos of the [[Cultural Revolution]], the sciences declined. In the field of mathematics, in addition to Chen Jingrun, Hua Luogeng, Zhang Guanghou and other mathematicians struggling to continue their work. After the catastrophe, with the publication of [[Guo Moruo]]'s literary "Spring of Science", Chinese sciences and mathematics experienced a revival. In 1977, a new mathematical development plan was formulated in Beijing, the work of the mathematics society was resumed, the journal was re-published, the academic journal was published, the mathematics education was strengthened, and basic theoretical research was strengthened.{{sfn|Kong|2015}}

An important mathematical achievement of the Chinese mathematician in the direction of the power system is how [[Xia Zhihong]] proved the [[Painleve conjecture]] in 1988. When there are some initial states of ''N'' celestial bodies, one of the celestial bodies ran to infinity or speed in a limited time. Infinity is reached, that is, there are non-collision singularities. The Painleve conjecture is an important conjecture in the field of power systems proposed in 1895. A very important recent development for the 4-body problem is that Xue Jinxin and Dolgopyat proved a non-collision singularity in a simplified version of the 4-body system around 2013.{{sfn|Kong|2012}}

In addition, in 2007, [[Shen Weixiao]] and Kozlovski, Van-Strien proved the [[Real Fatou conjecture]]: Real hyperbolic polynomials are dense in the space of real polynomials with fixed degree. This conjecture can be traced back to Fatou in the 1920s, and later Smale posed it in the 1960s. The proof of Real Fatou conjecture is one of the most important developments in conformal dynamics in the past decade.{{sfn|Kong|2012}}

=== IMO performance ===
In comparison to other participating countries at the [[International Mathematical Olympiad]], China has highest team scores and has won the all-members-gold IMO with a full team the most number of times.<ref>{{Cite web |title=Team Results: China at International Mathematical Olympiad |url=https://imo-official.org/country_team_r.aspx?code=CHN}}</ref>
