More on almost countably compact spaces

We study a recent general space of countably compact space called almost countably compact. A topological space X is almost countably compact space if for every countable open cover {U-n : n is an element of N} of X, there is a finite subfamily {U-ni}(i=1)(m), where m is an element of N such that X = (Ui=1Cl)-Cl-m(U-ni). In particular, we investigate this new class of spaces and some other properties in the view of regular cover notion and semiregulariz at ion topology.
