Summary: For each class \(\mathbf A\) of topological spaces we have a closure operation \([ ] : P(X) \to P(X)\), called \(\mathbf A\)-closure, where \(X\) is a topological space and \(P(X)\) is the power set of \(X\). In this paper we study the \(\mathbf A\)-compact spaces, i.e.

In 1962, J. M. G. Fell [5] indicated the important role played by certain topological spaces which, though locally compact in a specialized sense, do not, in general, satisfy even the weakest separation axiom. He called them "locally compact". These were called "punktal kompakt" by Flachsmeyer [6] and to avoid confusion, we shall call them pointwise ...

Publisher Summary This chapter focuses on compact spaces. A topological space which is the union of two compact sets is compact. The Cartesian product of compact spaces is a compact space. Every countable open cover contains a finite subcover. Obviously, a compact space is countably compact, while the converse is not true.

On almost compact and nearly compact spaces
Rendiconti del Circolo Matematico di Palermo, 1975A characterization of almost (resp. nearly) compact spaces and the product theorem for nearly compact spaces are obtained by means of the ϕ (resp. δ) convergence of filters.
