On asymmetric hypergraphs

Abstract

In this paper, we prove that for any k3k\ge 3, there exist infinitely many minimal asymmetric kk-uniform hypergraphs. This is in a striking contrast to k=2k=2, where it has been proved recently that there are exactly 1818 minimal asymmetric graphs. We also determine, for every k1k\ge 1, the minimum size of an asymmetric kk-uniform hypergraph.
