Monochromatic infinite sets in Minkowski planes

Nóra Frankl, Panna Gehér, Arsenii Sagdeev +1

We prove that for any $ℓ_{p}$ -norm in the plane with $1 < p < \infty$ and for every infinite $M \subset R^{2}$ , there exists a two-colouring of the plane such that no…

$t$ -sails and sparse hereditary classes of unbounded tree-width

Daniel Cocks

It has long been known that the following basic objects are obstructions to bounded tree-width: for arbitrarily large $t$ , $(1)$ the complete graph $K_{t}$ , $(2)$ the complete bipart…
