| Abstract: | In this paper mesocompactness is characterized in term of well-monotonecover, interior-preserving cover,suborthocompact and cushioned refinement,which improves the results of Guoshi Gao and Lisheng Wu.We prove that aspace is mnesocompact if and only if it is meso-expandable and has properly,which improves the result of JiGuang Jiang. |
