The lattice of pretopologies on an arbitrary set S

Allan Matlock Weber Carstens

Vol. 29 (1969), No. 1, 67–71
Abstract

The structure of the lattice of pretopologies on the set S, unlike that of the lattice of topologies on S (a proper sublattice of the former), has not been closely examined. We establish that pretopologies may be identified with products of certain filters in a natural way. From this identification, we are able to determine much of the structure of this lattice.
