About G2A2

"Groups and Graphs, Algebras and Applications", G2A2–2025, belongs to the G2-series including international conferences and summer schools. Since 2014, the G2-events were held in Russia and China, and in Slovenia as satellite events of the 8th European Congress of Mathematics. For more details, see Useful links.

G2A2–2025 aims to bring together experts, young researchers and students from different fields of mathematics and their applications mainly based on algebra and group theory, geometry and algebraic graph theory, topology and algebraic combinatorics, coding theory and theory of computational complexity, especially those involving group actions on combinatorial objects.

The official language of the event is English.

Venue

All scientific activities take place at Novosibirsk State University, August 3−17, 2025.
August 3 is the day to arrive and August 17 is the day to leave, that is, there are no activities on these days.

Program

The program of the G2A2−2025 consists of 50-minute invited talks and 25-minute contributed talks in the frame of the International Conference and 4 minicourses in the frame of the PhD-Master Summer School.
