Abstract:
In this paper, a space with a closed image of a locally compact metric space is obtained if and only if it is a Frechet space with a point-countable weak-compact k-network, it is a new characterization of closed images with locally compact metric spaces by means of weak-compact k-networks.[著者文摘]
Key words:
locally compact metric spaces; closed images; k-networks; weak-compact k-networks
