Actually, Skk characterizes the strongly k−separating objects of the family of digital surfaces, defined by means of continuous analogues, of the universal (k, k)−spaces introduced in [6].application/pdfengAtribución-NoComercial-SinDerivadas 4.0 Españahttp://creativecommons.org/licenses/by-nc-nd/4.0/Discrete surfaceContinuous analogueStrong separationinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
