Turán Densities for Small Hypercubes

David Ellis, Maria-Romina Ivan, Imre Leader

How small can a set of vertices in the $n$ -dimensional hypercube $Q_{n}$ be if it meets every copy of $Q_{d}$ ? The asymptotic density of such a set (for $d$ fixed and $n$ large) is den…

Block Sizes in the Block Sets Conjecture

Maria-Romina Ivan, Imre Leader, Mark Walters

A set $X$ is called Euclidean Ramsey if, for any $k$ and sufficiently large $n$ , every $k$ -colouring of $R^{n}$ contains a monochromatic congruent copy of $X$ . This notion w…

Turán Densities for Daisies and Hypercubes

David Ellis, Maria-Romina Ivan, Imre Leader

An $r$ -daisy is an $r$ -uniform hypergraph consisting of the six $r$ -sets formed by taking the union of an $(r - 2)$ -set with each of the 2-sets of a disjoint 4-set. Bollobás, Leader…
