Vertex-Ramsey theorems for Cartesian powers of graphs

Nóra Almási, Maria Axenovich, Arsenii Sagdeev

For graphs $G, H$ and positive integers $r$ and $n$ we write $G^{□ n} r H$ if every $r$ -vertex-coloring of the Cartesian power $G^{□ n}$ of $G$ contains a…

Online Ramsey turnaround numbers

NÃ³ra AlmÃ¡si, Maria Axenovich

The online Ramsey turnaround game is a game between two players, Builder and Painter, on a board of $n$ vertices using $3$ colors, for a fixed graph $H$ on at most $n$ vertices. Th…

Alternating odd cycles and orientations of Kneser-like graphs

NÃ³ra AlmÃ¡si, GÃ¡bor Simonyi

We call an oriented odd cycle alternating if it has exactly one vertex whose in-degree and out-degree are both positive. In this paper, we investigate whether certain graphs admit…
