Locally closed space
WitrynaAn //-closed space is shown to be compact if and only if every open subset is locally H-closed. A retract of a locally //-closed space is locally //-closed. 1. Introduction Recall that a space is said to be H-closed iff it is a closed subspace of every Hausdorff embedding space. A space is locally H-closed, or LHC, iff every point WitrynaFor locally-compact spaces, we know that there is only one one-point com-pactification. For locally-//-closed spaces, F. Obreano [1] and J. Porter [2] have shown that there may not be a unique one-point 77-closed extension. Locally-i/-closed spaces, however, do possess a projective maximum and also a projective minimum one-point /f-closed ...
