Abstract:
The not ions of base-met acompact(mesocompact)space and base-met acompact(mesocompact) mapping are int roduced.It is invest igated that base-met acompactness and base-mesocompact ness are inversely preserved under perfect mapping,closed Lindelêf mapping,base-paracompact mapping,base2metacompact mapping and base-mesocompact mapping.
