Local Pre-Hausdorff Objects in the Category of Interval Spaces

Abstract

In this paper, we characterize the local $T_{0}$, $T_{1}$, pre-Hausdorff and Hausdorff objects in the topological category of interval spaces and interval-preserving maps and investigate the relationships among them. Then, we show that all these objects are hereditary and productive.
