2050, South Africa.0000-0002-8649-5635Journal Article20190905The concept of gluing a family of $T_0$-quasi-metric spaces along subsets was introduced by Otafudu. In this article, we continue the study of externally Isbell-convex and weakly externally Isbell-convex subsets of a $T_0$-quasi-metric space. We finally investigate some properties of the resulting $T_0$-quasi-metric space obtained by gluing a family of Isbell-convex $T_0$-quasi-metric spaces attached<br />along isometric subspaces.https://www.kjm-math.org/article_97193_f40ec285c7f66495a0dc6501643590b4.pdf
