# Variants on Digital Covering Maps

## TL;DR

This paper explores different variants of digital covering maps, establishing their equivalences and addressing limitations in previous work to advance understanding in digital topology.

## Contribution

It clarifies the relationships among various digital covering map variants and corrects inaccuracies in Han's earlier analysis.

## Key findings

- Established equivalences among digital covering map variants
- Identified and discussed shortcomings in Han's original paper
- Provided clearer framework for digital covering maps

## Abstract

SE Han's paper [11] discusses several variants of digital covering maps. We show several equivalences among these variants and discuss shortcomings in Han's paper.
