Abstract

Given non-negative integers nin_{i} and αiα_{i} with 0≤αi≤ni0 \leq α_{i} \leq n_i (i=1,2,...,k)(i=1,2,...,k), an [α1,α2,...,αk][α_{1},α_{2},...,α_{k}]-kk-partite hypertournament on ∑1kni\sum_{1}^{k}n_{i} vertices is a (k+1)(k+1)-tuple (U1,U2,...,Uk,E)(U_{1},U_{2},...,U_{k},E), where UiU_{i} are kk vertex sets with ∣Ui∣=ni|U_{i}|=n_{i}, and EE is a set of ∑1kαi\sum_{1}^{k}α_{i}-tuples of vertices, called arcs, with exactly αiα_{i} vertices from UiU_{i}, such that any ∑1kαi\sum_{1}^{k}α_{i} subset ∪1kUi′\cup_{1}^{k}U_{i}^{\prime} of ∪1kUi\cup_{1}^{k}U_{i}, EE contains exactly one of the (∑1kαi)!(\sum_{1}^{k} α_{i})! ∑1kαi\sum_{1}^{k}α_{i}-tuples whose entries belong to ∪1kUi′\cup_{1}^{k}U_{i}^{\prime}. We obtain necessary and sufficient conditions for kk lists of non-negative integers in non-decreasing order to be the losing score lists and to be the score lists of some kk-partite hypertournament.
