Resumen:
Let $n,k,r$ be positive integers, with $n geq kr$. The $r$-uniform Kneser hypergraph $KG^r(n,k)$ has as vertex set the set of all $k$-subsets of the set ${1,ldots,n}$ and its (hyper) edges are formed by the $r$-tuples of pairwise disjoint $k$-subsets of the set ${1,ldots,n}$. In this paper, we give conditions for the existence of homomorphisms between uniform Kneser hypergraphs.
