Title: Algebraic K-theory and Congruent Number

Keynote Speaker: Qin Hourong

Abstract: During this Forum, we will introduce the origin of the algebraic K-theory, and talk about the number theoretical significance of the Milnor group of algebraic integer rings. In combination with a new discriminant rule which we have recently obtained, we will establish a relation between Milnor group and congruent number.

Speaker Introduction: Qin Hourong, professor, head of the Department of Mathematics at Nanjing University, chairman of the Jiangsu Mathematical Society, executive director of the Chinese Mathematical Society, and editor of SCIENCE CHINA Mathematics. In 1999, he won the award of National Science Fund for Distinguished Young Scholars, and in 2004, he was appointed as the distinguished professor of Changjiang Scholars Program of the Minister of Education. He was selected into the first batch of "Hundred/Thousand/Ten-thousand Talents Program" (2004), and enjoyed special allowance from the State Council.

He mainly studies algebraic number theory and algebraic K-theory, and has obtained numerous research findings in the congruent number which remains long discussed; made original work, and carried on a great deal of follow-up work in Milnor core and Tate core of the number field; solved multiple conjectures proposed by Tankyee, Browkin, etc.; made a breakthrough in the study of Mazur conjecture of the famous elliptic curve Anomalous prime number. He has published dozens of papers in internationally well-known journals with research results exerting extensive and positive influences among international counterparts, which are called "Qin's Method" by foreign counterparts. In addition, he has been invited for giving a speech at high-level international academic conferences.
