**Nonstandard Analysis in Topology**

by Sergio Salbany, Todor Todorov

**Publisher**: arXiv 2011**Number of pages**: 48

**Description**:

We present Nonstandard Analysis in the framework of the superstructure of a given infinite set. We also present several applications of this axiomatic approach to point-set topology. Some of the topological topics such as the Hewitt real compactification and the nonstandard characterization of the sober spaces seem to be new in the literature on nonstandard analysis.
