Synopsis

This paper discusses the relationship between the uniqueness and the ordering of strictly positive solutions of elliptic predator-prey interacting systems. If (ū, v) and (u#, v#) are two such solutions with ū ≧ u# or vv#, then ū ≡= u#, vv#. When the positive solutions are numerically close to the extreme case, the solution is unique.
