We state the Eilenberg-Steenrod axioms and the Universal Coefficient Theorem for this cohomology theory. We show that the Künneth formula doesn't hold. A cup product is dened and its main properties are proved.eninfo:eu-repo/semantics/closedAccessCup product.Digital imageDigital simplicial cohomology groupKünneth formulaUniversal Coefficient TheoremArticle1611028Q1
