On Monday afternoon, a session is planned to present the open problems and partition the participants into small groups for research sessions. Each day, an update meeting will take place in the afternoon to report the progress of each group. As for previous sessions, each group will manage individually the working sessions his own way. text/html 2026-04-12T15:17:33+00:00 ross.kang (ross.kang@undisclosed.example.com) https://sparse-graphs.mimuw.edu.pl/doku.php?id=start&rev=1776007053&do=diff A Sparse (Graphs) Coalition This is a Europe-centred network of researchers, formed in 2020 to stimulate research and collaboration in graph theory, particularly through remote means. <https://arxiv.org/abs/2112.05042> Aims and Format The main goal of the network is, interactively, to learn, prove, conjecture in central subareas of graph theory. Subsidiary aims are to encourage active participation and mixing of diverse researchers (especially in terms of seniority, geography, expertise), to… text/html 2025-09-23T07:03:36+00:00 ross.kang (ross.kang@undisclosed.example.com) https://sparse-graphs.mimuw.edu.pl/doku.php?id=sessions:2024sessions:2024session1&rev=1758611016&do=diff 2024 Session 1 : Algebraic, extremal, and structural methods and problems in graph colouring Our overall aim is to bring researchers from algebraic combinatorics and extremal and structural graph theory together to work on open problems in chromatic graph theory.
