Xi Nanhua received a doctorate in mathematics from East China Normal University on 1988, and became a researcher at the Institute of Mathematics on 1994. In the same year, he won the first National Outstanding Youth Fund.
In 200 1 year, he won the silver prize of Morningside Mathematics Award (Global Chinese Mathematics Award) of the 2nd World Congress of Chinese Mathematicians.
Xi Nanhua's research on algebraic groups and quantum groups is a focus field in the current mathematics field, which brings together a group of world-renowned mathematicians, such as Kazhdan (Harvard University), Lusztig (Massachusetts Institute of Technology) and Langlands (Princeton University). Fields Prize winners Deligne and Delinfeld; ; Nakajima, Kyoto University (one-hour speaker at the 2002 International Congress of Mathematicians), etc. In such an extremely competitive field, Xi Nanhua has made a series of excellent research results through its own efforts. He proved the Lusztig conjecture about the base ring of affine A-type Weyl group, which became one of the foundations of many subsequent works in the world and an important contribution to algebraic group theory.
In 2007, another work of researcher Xi Nanhua was published in Journal of American Mathematical Society (Volume 20,No. 1, 2007), the top international mathematical journal. This is the first time that Chinese mainland scholars have independently published a paper on JAMS.
The 10th Chen Shengshen Mathematics Award ceremony was held in Weihai, Shandong Province, and mathematicians Xi Nanhua and Duan Haibao won the prize.
Xi Nanhua's research has been recognized by the international mathematics community. 1994 published a book of 137 pages in springer Publishing House. In 2002, he published a 95-page monograph at the American Mathematical Society. But from 1990 to now, he has only published 18 papers.
