We organise the International Conference and PhD-Master Summer School
"Graphs and Groups, Complexity and Convexity", which belongs to the G2-series of international conferences and summer schools.
Since 2014, the G2-events were held in Russia, China, and Slovenia (see
history of G2 for details).
G2C2-2024 aims to cover modern aspects of graph theory, group theory, complexity theory, convexity theory, and their connections.
All scientific activities will take place at the School of Mathematical Sciences of Hebei Normal University
(see
Baidu maps and
Google maps) on August 12-24, 2024 (August 11 is the day to arrive and August 25 is the day to leave, that is, there will be
no activities on these days).
The official language of the event is English.
The
program of the event includes 50-minute plenary talks, 25-minute contributed talks and minicourses.
