June 15th, Peking University officially issued a statement stating that Peking University Boya Distinguished Professor and School of Mathematical Sciences Deputy Dean Liu Ruochuan has made important progress in research in the field of arithmetic geometry. The research results have recently been published by the top international mathematics journal Journal Accepted by the American Mathematical Society (JAMS). Played a key role in the recent breakthrough work of Pila-Shankar-Tsimerman on the Andre-Oort conjecture of arbitrary village clusters. The reviewer of
commented that this paper is "absolutely an amazing paper", "the results are beautiful, the methods and techniques are powerful", and "it will become a classic paper in the field".
The paper completed by Liu Ruochuan and his collaborators was accepted by JAMS
p into the Hodge theory research field.
Liu Ruochuan is a world-class expert in the field of Hodge theory research. He is currently the Boya Distinguished Professor and Vice Dean of the School of Mathematical Sciences at Peking University. Gold medal winner of the 40th International Mathematical Olympiad.
Liu Ruochuan has long been working in the fields of arithmetic geometry and algebraic number theory, "producing the best research results in China." Liu Ruochuan has been working in related fields for many years. His independently completed "p-advanced Hodge theory and its application" project won the 2020 National Natural Science Award second prize. In recent years, Liu Ruochuan has gradually expanded his research field to related issues such as p-adic automorphic forms and algebraic topology, and has achieved fruitful results.
Liu Ruochuan’s independently completed project “p-advanced Hodge Theory and Its Application” won the second prize of the 2020 National Natural Science Award.
Liu Ruochuan has been exposed to the Mathematics Olympiad since the fourth grade of elementary school. “Falling in love with mathematics is a very natural thing. If I have to name one reason, it would be interest. "When he was in elementary school, Liu Ruochuan showed great talent in mathematics and liked to challenge difficult problems. "I thought about it for several hours a day and couldn't figure it out, so I just thought about it the next day. I might have been thinking about it for a year, and suddenly one day it suddenly dawned on me." Later, Liu Ruochuan won the gold medal in the International Mathematical Olympiad and was recommended to Peking University Mathematical Sciences I studied in the college and completed all undergraduate and master’s courses within 5 years.
When Liu Ruochuan was studying for his PhD at Peking University Beijing International Mathematics Research Center
Liu Ruochuan, who was interested in arithmetic and geometry, was inspired by his teacher to open the door to studying p-Hodge theory. After graduating from the Ph.D., he collaborated with his mentor on related research, and finally achieved basic and breakthrough results. A foreign professor commented this way: Liu Ruochuan is one of the best world-class experts in the field of p-Hodge theory research.
once said that the study of mathematics cannot be limited to "useful learning"
When it comes to mathematics, many people often think of formulas and calculations first, but these are not all mathematics. "Calculation is important, but what is more important is the principle and structure behind the calculation." Liu Ruochuan said, "For example, for mathematicians, they notice that 3+5=5+3, and then conclude that a+b= The law b+a may be far more important than knowing 3+5=8. "
In Liu Ruochuan's mind, even though the conjectures or theories sometimes proposed cannot find their counterparts in real life, "but they are very beautiful and represent human beings." The height of spiritual civilization proves the power of human thinking or spiritual power. "Liu Ruochuan hopes that his knowledge will still be valuable after many years. "I think this is also the dream of all scientists."
For basic research such as mathematics. , Liu Ruochuan believes that we should not dwell on the so-called "useful" or "useless". "Mathematics can work on different subjects, but what subjects it will work on and in what way it will work are not something people can predict in advance." Liu Ruochuan said, Einstein The mathematics needed to establish general relativity The tool " Riemannian geometry " was created by the German mathematician Riemann decades ago. Although there were already physical considerations when Riemann created this knowledge, it took decades for it to really come into use.
"If we stick to the so-called 'useful learning', we may always follow others and even risk stagnating." Liu Ruochuan said.
