Ramsey numbers for 1-degenerate 3-graphs

Peter Allen, Simona Boyadzhiyska, MatÃas Pavez-SignÃ©

We construct a 3-uniform 1-degenerate hypergraph on $n$ vertices whose 2-colour Ramsey number is $I^c ◯ (n^{3/2} / lo g n)$ . This shows that all remaining open cases of the hyper…

Odd-Ramsey numbers of Hamilton cycles

Simona Boyadzhiyska, Shagnik Das, Thomas Lesgourgues +1

The odd-Ramsey number $r_{o dd} (n, H)$ of a graph $H$ , as introduced by Alon in his work on graph-codes, is the minimum number of colours needed to edge-colour $K_{n}$ so that ev…
