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.
