The π Images of Locally Compact Metric Spaces
Peng Yi-qing · 2007
This paper mainly discusses characterizations of sequentially quotient and the sequentially covering Л images of locally compact metric spaces in the notion of finite-directed refinement.A space X is a sequentially quotation(the sequentially covering) π image locally-compact metric spaces if and only if X has a point-star network which cs covering of finite-directed refinement made of compact sets.
