2020 Second Prize of National Natural Science Award is awarded to Prof. Tian Ye for his extraordinary achievements in the Congruent number problem and arithmetic of L-function.
The congruent number problem, originated in an Arab manuscript dated A.C. 972, is one of the oldest unsolved major problems in number theory, and possibly in the whole of mathematics. It is closely related to the Birch and Swinnerton-Dyer conjecture, one of the seven Millennium Prize Problems.
As part of the Paris Agreement, nearly all countries agreed to take steps to limit the average increase in global surface temperature to less than 2 °C, or preferably 1.5 °C, compared with preindustrial levels. Since the Agreement was adopted, however, concerns about global warming suggest that countries should aim for the “preferable” warming limit of 1.5 °C.
What are the implications for China of trying to achieve this lower limit?

The AMSS is not only an influential research center, but a high level graduate education base. Its four institutes are among the first authorized to confer master’s degrees and doctorates, and were among the earliest post-doctoral stations.
The Academy of Mathematics and Systems Science (AMSS) of the Chinese Academy of Sciences (CAS), was founded in December 1998 with the integration of the Institute of Mathematics (established 1952), the Institute of Applied Mathematics (established 1979), the Institute of Systems Science (established 1979), the Institute of Computational Mathematics and Scientific/Engineering Computing (established 1995). CAS Academician Prof. YANG Lo was its founding president, CAS Academician Prof. GUO Lei was the second president, CAS Academician Prof. XI Nanhua and Prof. WANG Yuefei were the third co-presidents, and CAS Academician Prof. XI Nanhua is the current president.
