The International Consortium of Chinese Mathematicians was founded in 2016, with the purpose of promoting and advancing mathematics within the extended Chinese community, and building good relationships between Chinese mathematicians and other mathematicians throughout the world. The first meeting of the Consortium was held in December 2017 at Sun Yat-sen University in Guanzhou, Guangdong, with about 150 mathematicians presenting their outstanding works in various branches of mathematics, ranging from number theory to geometry, analysis, and applied mathematics. This volume presents 30 expository papers by speakers at the meeting, based upon their lectures given there.
