[HTML][HTML] Multicolour Ramsey numbers of odd cycles

AN Day, JR Johnson - Journal of Combinatorial Theory, Series B, 2017 - Elsevier
We show that for any positive integer r there exists an integer k and a k-colouring of the
edges of K 2 k+ 1 with no monochromatic odd cycle of length less than r. This makes …

Gallai–Ramsey number of odd cycles with chords

F Zhang, ZX Song, Y Chen - European Journal of Combinatorics, 2023 - Elsevier
A Gallai coloring is a coloring of the edges of a complete graph without rainbow triangles,
and a Gallai k-coloring is a Gallai coloring that uses at most k colors. For an integer k≥ 1 …
