Xiuxiong Chen (Chinese: 陈秀雄; pinyin: Chén Xiùxióng) is a Chinese-American mathematician whose research concerns differential geometry and differential equations.[1] A professor at Stony Brook University since 2010, he was elected a Fellow of the American Mathematical Society in 2015 and awarded the Oswald Veblen Prize in Geometry in 2019.
Biography
Chen was born in Qingtian County, Zhejiang, China.[2] He entered the Department of Mathematics of the University of Science and Technology of China in 1982,[3] and graduated in 1987.[2] He subsequently studied under Peng Jiagui (彭家贵) at the Graduate School of the Chinese Academy of Sciences, where he earned his master's degree.[2]
In 1989, he moved to the United States to study at the University of Pennsylvania.[2] The last doctoral student of Eugenio Calabi,[2][4] he obtained his Ph.D. in mathematics in 1994, with his dissertation on "Extremal Hermitian Matrices with Curvature Distortion in a Riemann Surface".[4]
Chen was an instructor at McMaster University in Canada from 1994 to 1996. For the next two years he was a National Science Foundation postdoctoral fellow at Stanford University. He was as an assistant professor at Princeton University from 1998 to 2002, before becoming an associate professor at the University of Wisconsin–Madison. He was promoted to full professor in 2005. Since October 2010 he has been a professor at Stony Brook University.[5] In 2006, he founded the Pacific Rim Conference on Complex Geometry at the University of Science and Technology of China.[2]
As of 2019, Chen has advised 17 Ph.D. students, including Song Sun (孙崧) and Bing Wang (王兵).[2][4] He was elected a Fellow of the American Mathematical Society in 2015 "for contributions to differential geometry, particularly the theory of extremal Kahler metrics".[6] He was an invited speaker at the 2002 International Congress of Mathematicians, in Beijing.[7]
Conjecture on Fano manifolds and Veblen Prize
In 2019, Chen was awarded the prestigious Oswald Veblen Prize in Geometry, together with Simon Donaldson and Chen's former student Song Sun, for proving a long-standing conjecture on Fano manifolds, which states "that a Fano manifold admits a Kähler-Einstein metric if and only if it is K-stable". It had been one of the most actively investigated topics in geometry since its proposal in the 1980s by Shing-Tung Yau after he proved the Calabi conjecture. It was later generalized by Gang Tian and Donaldson. The solution by Chen, Donaldson and Song was published in the Journal of the American Mathematical Society in 2015 as a three-article series, "Kähler–Einstein metrics on Fano manifolds, I, II and III".[8][9]
