Hypergraphical t-designs

Abstract

AbstractWe introduce a theory of hypergraphical t-designs. We show the existence of these designs and prove a finiteness theorem on these designs for infinitely many parameter sets. We also give effective bounds on the number of points in these cases. These results generalize some results on graphical t-designs of Alltop, Chee and Betten–Klin–Laue–Wassermann
