We examine general topological properties of those spaces and give some inclusion theorems. Furthermore, we deal with their dual spaces.eninfo:eu-repo/semantics/closedAccessDouble sequenceAlmost convergenceStrongly almost convergenceDifference sequence spaceDual spaceOn the difference spaces of almost convergent and strongly almost convergent double sequencesArticle23249350610.1007/s11117-018-0620-32-s2.0-85055706638Q2WOS:000462665400016Q2
