There are many papers in the literature about blocking sets in hypergraphs, including Steiner systems (see references). In this paper we study the existence of equi-blocking sets in K_(2,2)-designs and in K_(3,3)- designs, determining the spectrum. Further we determine K_(2,2)-designs and K_(3,3)-designs having blocking sets of all the possible cardinalities.

Abstract
There are many papers in the literature about blocking sets in hypergraphs, including Steiner systems (see references). In this paper we study the existence of equi-blocking sets in K_(2,2)-designs and in K_(3,3)- designs, determining the spectrum. Further we determine K_(2,2)-designs and K_(3,3)-designs having blocking sets of all the possible cardinalities.File in questo prodotto:
