We show that some of the published assertions based on these tools are incorrect or trivial; we offer improvements on others.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Digital topologyFixed pointMetric spaceRemarks on fixed point assertions in digital topologyArtÃculo2019-04-0410.4995/agt.2019.10474Abierto1989-4147
