The International Conference and PhD-Master Summer School on Graphs and Groups, Representations and Relations

G2R2 is the International Conference and PhD-Master Summer School on Graphs and Groups, Representations and Relations which will be held on August 06-19, 2018, in Akademgorodok, Novosibirsk, Russia.

The G2R2-events will take place in Novosibirsk State University (NSU).

The main goal of these international interdisciplinary events is to bring together researchers from different fields of mathematics and its applications mainly based on graph theory, group theory and low dimensional geometry and topology, especially those involving group actions on combinatorial objects.

The scientific program consists of the G2R2-Conference and the G2R2-Summer School according to the G2R2-Timetable.

The scientific program of the G2R2-Conference consists of plenary and contributed talks.
