Research output: Contribution to journalArticlepeer-review


We deal with an extremal problem concerning panchromatic colorings of hypergraphs. A vertex r-coloring of a hypergraph H is panchromatic if every edge meets every color. We prove that for every [Formula presented], every n-uniform hypergraph H with [Formula presented] has a panchromatic coloring with r colors, where c>0 is an absolute constant.
