Recall that a collection 79 of subsets of a space is star-countable if each element of 7 ~ meets at most countably many other elements of 79. We characterize the closed image of a locally separable metric space as a Frrchet space with a star-countable k-network, and give a characterization for the p

Let X be a space, and C be a closed cover of X consisting of metric subsets. Let X have the weak topology with respect to C in the sense of K. Morita. In terms of k-networks, we give some topological properties on X by means of the covering properties associated with the cover C.
