Abstract

If ℝn is partially ordered by a generating closed cone K; then (ℝn;K) is a pre-Riesz space. We show for a disjointness preserving bijection T on (ℝn;K) that the inverse of T is also disjointness preserving. We prove that for T there is k ∈ P(b) such that Tk is band preserving, where b is the number of bands in (ℝn;K); and P(b) the set of orders of permutations on b symbols.
