On completeness of H-closed pospaces

General Topology 2017-07-19 v1

Abstract

We generalized the characterization of H-closedness for linearly ordered pospaces as follows: A pospace XX without an infinite antichain is an H-closed pospace if and only if XX is a directed complete and down-complete poset such that sup LL and inf LL are contained in the closure of LL for any nonempty chain LL in XX.
