We also obtain a new version of the Orlicz-Pettis theorem within the frame of the f-statistical convergence.eninfo:eu-repo/semantics/closedAccessStatistical convergenceOrlicz-Pettis Theoremweakly unconditionally Cauchy seriescompletenessMultiplier Sequence Spaces Defined by Statistical Summability and Orlicz-Pettis TheoremArticle42121410142210.1080/01630563.2021.19618032-s2.0-85112434809Q2WOS:000684726100001Q2
