Shou-Wu Zhang

Shou-Wu Zhang (; born October 9, 1962) is a Chinese-American mathematician known for his work in number theory and arithmetic geometry. He is currently a Professor of Mathematics at Princeton University.

Biography

Early life

Shou-Wu Zhang was born in Hexian, Ma'anshan, Anhui, China, on October 9, 1962. Zhang grew up in a poor farming household and could not attend school until eighth grade due to the Cultural Revolution. He spent most of his childhood raising ducks in the countryside and self-studying mathematics textbooks that he acquired from sent-down youth in trades for frogs. By the time he entered junior high school at the age of fourteen, he had taught himself calculus and had become interested in number theory after reading about Chen Jingrun's proof of Chen's theorem which made substantial progress on Goldbach's conjecture.

Education

Zhang was admitted to the Sun Yat-sen University chemistry department in 1980 after scoring poorly on his mathematics entrance examinations, but he later transferred to the mathematics department after feigning color blindness and received his bachelor's degree in mathematics in 1983. He then studied under analytic number theorist Wang Yuan at the Chinese Academy of Sciences where he received his master's degree in 1986. In 1986, Zhang was brought to the United States to pursue his doctoral studies at Columbia University by Dorian M. Goldfeld. He initially studied under Goldfeld and then Hervé Jacquet, before deciding to work with Lucien Szpiro, a visiting professor at Columbia at the time, and Gerd Faltings at Princeton University. He received his PhD at Columbia University under the supervision of Szpiro in 1991.

Career

Zhang was a member of the Institute for Advanced Study and an assistant professor at Princeton University from 1991 to 1996. In 1996, Zhang moved back to Columbia University where he was a tenured professor until 2013. He has been a professor at Princeton University since 2011 was named the Henry Burchard Fine Professor from 2014 to 2015, and was named a Eugene Higgins Professor in 2021.

Zhang is on the editorial boards of: '' Acta Mathematica Sinica'', '' Algebra & Number Theory'', '' Forum of Mathematics'', ''Journal of Differential Geometry'', ''National Science Review'', ''Pure and Applied Mathematics Quarterly'', ''Science in China'', and ''Research in Number Theory''. He has previously served on the editorial boards of: ''Journal of Number Theory'', ''Journal of the American Mathematical Society'', ''Journal of Algebraic Geometry'', and '' International Journal of Number Theory''.

Research

Zhang's doctoral thesis ''Positive line bundles on Arithmetic Surfaces'' proved a Nakai–Moishezon type theorem in intersection theory using a result from differential geometry already proved in Tian Gang's doctoral thesis. In a series of subsequent papers (, ), he further developed his theory of 'positive line bundles' in Arakelov theory which culminated in a proof of the Bogomolov conjecture with Emmanuel Ullmo and a further generalization of the Bogomolov conjecture ().

In 2001, Zhang proved a generalization of the Gross–Zagier theorem to modular abelian varieties of GL(2) type (). In particular, the result led him to a proof of the rank one Birch-Swinnerton-Dyer conjecture for modular abelian varieties of GL(2) type over totally real fields through his work relating the Néron–Tate height of Heegner points to special values of L-functions in . In 2013, Zhang and his former doctoral students Xinyi Yuan and Wei Zhang established a full generalization of the Gross–Zagier theorem to all Shimura curves ( ).

In arithmetic dynamics, posed conjectures on the Zariski density of non-fibered endomorphisms of quasi-projective varieties and proposed a dynamical analogue of the Manin–Mumford conjecture.

In 2018, proved the averaged Colmez conjecture which was shown to imply the André–Oort conjecture for Siegel modular varieties by Jacob Tsimerman.

Awards

Zhang has received a Sloan Foundation Research Fellowship (1997) and a Morningside Gold Medal of Mathematics (1998). He is also a Clay Foundation Prize Fellow (2003), Guggenheim Foundation Fellow (2009), Fellow of the American Academy of Arts and Sciences (2011), and Fellow of the American Mathematical Society (2016). He was an invited speaker at the International Congress of Mathematicians in 1998.
