Minimum Degrees of Minimal Ramsey Graphs for Almost-Cliques

Andrey Grinshpun, Raj Raina, Rik Sengupta

For graphs $F$ and $H$ , we say $F$ is Ramsey for $H$ if every $2$ -coloring of the edges of $F$ contains a monochromatic copy of $H$ . The graph $F$ is Ramsey $H$ -minimal if $F$ is R…

Sebastian A. Csar, Rik Sengupta, Warut Suksompong

We explore some of the properties of a subposet of the Tamari lattice introduced by Pallo, which we call the comb poset. We show that three binary functions that are not well-behav…
