| Abstract: | In this paper , We proves that maintain close sequence-covering mappings in sequential compactness times; As an application, closed sequence-covering mappings preserve sequnential submesocompactness. Also we prove that sequential submesocompaetness is inversely preserved under closed Lindelof mappings in regular spaces. |
