Soochow University

Abstract: In this paper, we discuss a class of spaces with a locally countable $sn$-network. We give some characterizations of this class and investigate variance and inverse invariance of this class under certain mappings.

Keywords: $sn$-network, $cs$-network, weak-base, perfectmapping, (strongly) Lindelöf mapping, finite subsequence-covering mapping.
