Abstract

In this study we introduce the notions of semi-homotopy of semi- continuous maps and of semi-paths. We also construct a group structure, which will be called semi-fundamental group, using semi-loops and explore some properties of semi-homotopy and semi-fundamental groups.

Keywords

Semi-open sets, semi-closed sets, homotopy, fundamental groups
