摘要

对于每一个正整数，我们在数字空间\({\mathbb {Z}}^3\)中引入一个邻接关系。然后使用所获得的图中的连通性来定义和研究数字乔丹曲面。这些表面是作为包围数字多面体的多面体表面获得的，这些数字多面体可以与数字立方体、三角棱镜、方形金字塔和四面体面对面平铺。

Adjacencies for recognition of digital Jordan surfaces

For every positive integer, we introduce an adjacency in the digital space \({\mathbb {Z}}^3\). Connectedness in the graph obtained is then used to define and study digital Jordan surfaces. The surfaces are acquired as polyhedral surfaces bounding the digital polyhedra that can be face-to-face tiled with digital cubes, triangular prisms, square pyramids, and tetrahedra.
