Then we define ring and algebra structures of a digital cohomology with the cup product. Finally, we prove a special case of the Borsuk-Ulam theorem for digital images.eninfo:eu-repo/semantics/closedAccessDigital simplicial cohomology groupcup productcohomology ringcohomology algebraArticle432477499WOS:000403571400016Q4
