Abstract.  In this paper, we characterize pseudo-sequence-covering π-images of locally separable metric spaces by means of  fcs-covers and point-star networks. We also investigate pseudo-sequence-covering
π-s-images of locally separable metric spaces.

Keywords:  π-map;  s-map;  network;  k-cover;  cfp-cover;  fcs-cover;  cs*-cover;  pseudo-sequence-covering;  subsequence-covering;  sequentially-quotient.
