ICTP and the International Mathematical Union (IMU) have awarded the 2024 Ramanujan Prize for young mathematicians from developing countries to Ruochuan Liu of Peking University, China, for his fundamental contributions to p-adic Hodge theory, especially his foundational study of relative p-adic Hodge theory and his remarkable work on rigidity and the Riemann-Hilbert correspondence for p-adic local systems.
Liu is a professor at the Beijing International Center for Mathematical Research (BICMR) at Peking University. His current research interests are arithmetic geometry and algebraic number theory, with a focus on p-adic aspects of number theory and arithmetic geometry, especially p-adic Hodge theory, p-adic automorphic forms and the p-adic Langlands program.
Liu is considered to be one of the foremost arithmetic geometers working in China. His work has received the highest accolades from top mathematicians in the field of p-adic Hodge theory. Furthermore, for the past decade, he has played a major role developing arithmetic geometry in China.
Liu obtained his BSc and master's degree in mathematics from Peking University, and his PhD at MIT in 2008. He was a member of the Institute for Advanced Study in 2010; in 2012, he returned to BICMR, where he has made a series of breakthroughs in p-adic Hodge theory, automorphic forms and the Langlands program.
Liu's work has received a number of recognitions, including the 2020 China Youth Science and Technology Award, the 2019 Tencent Xplorer prize, and the 2017 National Science Fund Award for Distinguished Young Scholars.
The Ramanujan Prize award ceremony will take place later in 2024.
About the Ramanujan Prize
The Ramanujan Prize for young mathematicians from developing countries has been awarded annually since 2005 and is administered jointly by ICTP and IMU. It is usually awarded to one person, but may be shared equally among recipients who have contributed to the same body of work.
The Prize is awarded to a researcher from a developing country who is less than 45 years of age on 31 December of the year of the award, and who has conducted outstanding research under difficult conditions in a developing country. Researchers working in any branch of the mathematical sciences are eligible. The Prize carries a $10,000 cash award.
The Prize selection committee consists of eminent mathematicians appointed in consultation between the ICTP and the IMU.
