Abstract

Class field theory is one of the greatest achievements in number theory. It culminated in the early 20th century, and has roots all the way back in the work of Gauss; in fact the several aspects of the work of Gauss on number theory are unified by class field theory. We will survey the history of this fascinating and breathtakingly beautiful subject, through the life and work of mainly seven mathematicians from Kronecker to Chevalley. The lecture will be in Chinese.
