The size-Ramsey number of powers of paths

Dennis Clemens, Matthew Jenssen, Yoshiharu Kohayakawa +4

Given graphs $G$ and $H$ and a positive integer $q$ say that $G$ is $q$ -Ramsey for $H$ , denoted $G \to (H)_{q}$ , if every $q$ -colouring of the edges of $G$ contains a monochro…

Ramsey Numbers of Connected Clique Matchings

Barnaby Roberts

We determine the Ramsey number of a connected clique matching. That is, we show that if $G$ is a $2$ -edge-coloured complete graph on $(r^{2} - r - 1) n - r + 1$ vertices, then there i…

Partite Saturation Problems

Barnaby Roberts

We look at several saturation problems in complete balanced blow-ups of graphs. We let $H [n]$ denote the blow-up of $H$ onto parts of size $n$ and refer to a copy of $H$ in $H [n]$ …
