DIGITAL HOMOLOGY GROUPS OF DIGITAL WEDGE SUMS
Jeang Min Kang, Sang-Eon Han · Honam Mathematical Journal · 2016
The present paper investigates some properties of the digital homology in [1, 4, 5] and points out some unclearness of the definition of a digital homology and further, suggests a suitable form of a digital homology. Finally, we calculate a digital homology group and a relative digital homology group of some digital wedge sums. Finally, the paper corrects some errors in [6]. In the present paper all digital images (X, k) are assumed to be non-empty and k-connected.
