Hua Luogeng

From Wikipedia, the free encyclopedia

Hua Luogeng or Loo-keng (Simplified Chinese: 华罗庚; Traditional Chinese: 華羅庚; pinyin: Huà Luógēng) (November 12, 1910 - June 12, 1985) was a mathematician from China. He was the founder and pioneer of many fields in mathematical research. He wrote more than 200 papers and monographs, many of which became classic documents. Since his sudden death while giving a lecture in Japan, many mathematics secondary education programs have been named after him. In the early 1930's, his book on cumulative prime number theory has been influential to many subsequent number theorists in China, including renowned Chen Jingrun who obtained the best result so far in the binary Goldbach conjecture. Hua also made contributions to the development of college education in China. He was the first Chair of the Department of Mathematics and Vice President of University of Science & Technology of China (USTC), a new type of university established by the Chinese Academy of Sciences (CAS) in 1958 which was aimed at fostering skilled people necessary for the economic development, defense and education in science and technology.

Hua's father was a small businessman. Hua had a capable middle school math teacher who recognized his potential early, and encouraged him to read advanced texts. Hua was partially paralyzed in his late teenage, due to mistreatment in a prolonged illness during which he stayed in bed for half a year. His first significant result was concerned with a paper written by Dr. Su JiaJu who claimed to have a closed form radical solution of the quintics. Hua studied Abel's original paper on the unsolvability of quintics and found a miscalculation in a 13x13 matrix in Su's paper. Henceforth Hua published his rebuttal in an influential mathematics journal in China, which was noticed by some professors in Qinghua University, especially Dr. Xiong Qinglai.
