Suppose that V={1â, â…â, ân} is a non-empty set of n elementsâ, âA={A1â, â…â, âAm} a non-empty family of m non-empty subsets of Vâ, âand 2 ≤ d ≤ n a positive integerâ. âIn this paperâ, âwe investigate the question arises whether there exists a d-uniform hypergraph H with V(H)=V where A is the set whose elements are the minimal vertex cover sets of Hâ.
