Abstract:In this paper, we use the notion of refinement to describe the sequentially quotient and sequentially covering images of locally separable metric spaces. We proved that a space X is a sequentially quotient(sequentially covering) π images of locally separable metric spaces if X has a point-star network which is a countable refinement and cs(cs* ) refinement.
Keywords:locally separable metric space  sequentially quotient mapping  sequentially covering mapping  π mapping  cs(cs* ) refinement  point-star network
