Remarks on the digital-topological $k$ -group structures and the development of the $A P_{1}$ - $k$ - and $A P_{1}^{*}$ - $k$ -group

Sang-Eon Han

In the literature of a digital-topological ( $D T$ -, for brevity) group structure on a digital image $(X, k)$ , roughly saying, two kinds of methods are shown. Given a digital image $(…

Essential concepts of digital topology\\ (digital $k$ -connectivity and $k$ -adjacencis for digital products)

Sang-Eon Han

The paper refers to several concepts which are essential to studying digital objects from the viewpoint of digital topology: digital $k$ -connectivity or digital $k$ -adjacency, $C$ -…
