the following conjecture: If Y~ is a hereditary hypergraph on S and .gCcy~ is a family of maximum cardinality of pairwise intersecting members of ~, then there exists an xeS such that d~(x)=l{HeYe:xeH}l=l.al. Berge and Schrnheim proved that 1~1~Β½ I~el for every ~ and ~. Now we prove that if there ex
Let n, s, t be nonnegative integers with s L t < n and let V be an n-dimensional linear space over some finite field GF(q). Let 4 be a family of linear subspaces of V, which satisfies dim(F fl F') ~~t for all F, F' E 9. In this paper it is shown for n 291 that ifn+t-1 mod2, ifn+t=Omod2. Moreover, al
