Generalized Normal Product Adjacency in Digital Topology
Laurence Boxer
We study properties of Cartesian products of digital images for which adjacencies based on the normal product adjacency are used. We show that the use of such adjacencies lets us o…

Fundamental Groups and Euler Characteristics of Sphere-like Digital Images
Laurence Boxer, P. Christopher Staecker
The current paper focuses on fundamental groups and Euler characteristics of various digital models of the 2-dimensional sphere. For all models that we consider, we show that the f…
