| Abstract: | The sequential submesocompact spaces is studied by use of the technique invented by H.J.K.Junnila.The sequential submesocompactness is characterized by σ-clousure-preserving closed refinement.As an application,it is proved that the closed sequence-covering mappings preserve sequnential submesocompactness. |
