On Ramsey numbers of complete graphs with dropped stars

Jonathan Chappelon, Luis Pedro Montejano, Jorge Ramírez Alfonsín

Let $r (G, H)$ be the smallest integer $N$ such that for any $2$ -coloring (say, red and blue) of the edges of $K_n$ , $n ⩾ N$ , there is either a red copy of $G$ or a blue copy…

Ramsey for complete graphs with dropped cliques

Jonathan Chappelon, Luis Pedro Montejano, Jorge Luis Ramírez Alfonsín

Let $K_[k, t]$ be the complete graph on $k$ vertices from which a set of edges, induced by a clique of order $t$ , has been dropped. In this note we give two explicit upper bounds…
