The Cameron-Liebler problem for sets
Abstract
Cameron-Liebler line classes and Cameron-Liebler k-classes in PG(2k+1,q) are currently receiving a lot of attention. Here, links with the Erdo″s-Ko-Rado results in finite projective spaces occurred. We introduce here in this article the similar problem on Cameron-Liebler classes of sets, and solve this problem completely, by making links to the classical Erdo″s-Ko-Rado result on sets. We also present a characterisation theorem for the Cameron-Liebler classes of sets.
