A rainbow triangle in G is a triple of edges (e1,e2,e3) with ei ∈ Gi for each i and {e1,e2,e3} forming a triangle in V. The triples G not containing rainbow triangles, also known as Gallai colouring templates, are a widely studied class of objects in extremal combinatorics. In the present work, we fully determine the set of edge densities (α1,α2,α3) such that if>αin2 for each i and n is sufficiently large, then G must contain a rainbow triangle. This resolves a problem raised by Aharoni, DeVos, de la Maza, Montejanos and Šámal, generalises several previous results on extremal Gallai colouring templates, and proves a recent conjecture of Frankl, Győri, He, Lv, Salia, Tompkins, Varga and Zhu.05C35, 05D99, Extremal graph theory, Gallai colourings, Mantel’s theorem, Rainbow trianglesurn:nbn:se:umu:diva-224095 (URN)10.1007/s00493-024-00102-6 (DOI)001209613600001 ()2-s2.0-85191690527 (Scopus ID)Swedish Research Council, 2021-03687Olle Engkvists stiftelse, 213-0204Available from: 2024-05-16 Created: 2024-05-16 Last updated: 2024-10-28Bibliographically approvedLeedham-Green, C., Markström, K. & Riis, S.

We show that there exists a Condorcet domain of size 224 and that this is the largest possible size for 8 alternatives. Our search also shows that this domain is unique up to isomorphism. In this note we investigate properties of the new domain and relate them to various open problems and conjectures.The same call, in code.
