Some topological properties of the new almost convergent sets have been investigated as well as gamma- and beta-duals of the spaces f(u, v, Delta) and f s(u, v, Delta). Also, the characterization of certain matrix classes on/into the mentioned spaces has exhaustively been examined. Finally, some identities and inclusion relations related to core theorems are established.eninfo:eu-repo/semantics/closedAccessAlmost ConvergenceSchauder BasisBeta- And Gamma -DualsMatrix MappingsCore TheoremsArticle1912738Q4WOS:000348559000002Q3
