A parity ErdÅs-Hajnal theorem for $t$ -intersecting curves

Andrew Suk, Su Zhou

For every fixed $t \geq 1$ , we prove a parity analogue of the mighty ErdÅs-Hajnal property for $t$ -intersecting curves in the plane. Let $B$ be a set of blue curves and $\m…

Extremal structure in dense arrangements of $k$ -intersecting curves

Andrew Suk, Su Zhou

Let $P$ be a set of $n$ points in the plane, and let $C$ be a collection of $n$ simple $k$ -intersecting curves, meaning that every two distinct curves of $C$ meet…

Unavoidable patterns and plane paths in dense topological graphs

BalÃ¡zs Keszegh, Andrew Suk, GÃ¡bor Tardos +1

Let $C_{s, t}$ be the complete bipartite geometric graph, with $s$ and $t$ vertices on two distinct parallel lines respectively, and all $s t$ straight-line edges drawn between them…

3-uniform monotone paths and multicolor Ramsey numbers

Andrew Suk, Ji Zeng

The monotone path $P_{n + 2}$ is an ordered 3-uniform hypergraph whose vertex set has size $n + 2$ and edge set consists of all consecutive triples. In this note, we consider the colle…
