WebIt proves that a linearly ordered topological space is not only normal but completely (or hereditarily) normal, i.e., if A, B are sets (not necessarily closed) such that A ∩ ˉB = B ∩ ˉA = ∅, then there are disjoint open sets U, V such that A ⊆ U and B ⊆ V. Without loss of generality, we assume that no point of A ∪ B is an endpoint of X. WebDe nition 1.1.
