Characterizations of spaces with $\sigma$-locally countable $sn$-networks
Sh. Xia College of Science, Shandong Jianzhu University, Jinan,
P. R. China
Abstract:
The concept of a $\sigma$-locally countable mapping is used for establishing relations between metric spaces and spaces with $\sigma$-locally countable $sn$-networks ($cs^*$-networks, weak bases).
Keywords:
$cs^*$-network, $sn$-network, weak base, $\sigma$-locally countable mapping, sequence-covering mapping.
