Sharp bounds for rainbow matchings in hypergraphs

Cosmin Pohoata, Lisa Sauermann, Dmitrii Zakharov

Suppose we are given matchings $M_{1}, ...., M_{N}$ of size $t$ in some $r$ -uniform hypergraph, and let us think of each matching having a different color. How large does $N$ need to be…

Convex polytopes from fewer points

Cosmin Pohoata, Dmitrii Zakharov

Let $E S_{d} (n)$ be the smallest integer such that any set of $E S_{d} (n)$ points in $R^{d}$ in general position contains $n$ points in convex position. In 1960, Erdős and S…
