Groups, Graphs and Combinatorics 2026— TU Dresden

GGC 26

April 20, 2026

organized by Vadim Alekseev, Manuel Bodirsky, Andreas Thom

Cayley graph of the alternating group A7

Overview

This is an informal one-day workshop to explore common themes and potential future collaboration around group theory, graph theory and combinatorics. Recent years have seen a number of exciting developments at the intersection of these fields, and we hope to bring together researchers from different backgrounds to discuss these developments and their potential applications.
