Title: KINGS IN MULTIPARTITE TOURNAMENTS AND HYPERTOURNAMENTS
Abstract: 
A vertex v of a digraph D is an s-king if d(v, u) ≤s for every vertex u∈V(D) where d(v, u) denotes the distance from v to u. Various results and open questions concerning the existence and the distributions of s-kings in multipartite tournaments and hypertournaments and related problems will be presented.
