Also, we obtain rates of A-statistical convergence of a double sequence of fuzzy positive linear operators for four-dimensional summability matrices.enA-Statistical convergence for double sequencesFuzzy positive linear operatorsFuzzy Korovkin theoryRates of A-statistical convergence for double sequencesRegularity for double sequencesArticle2-s2.0-84879326839WOS:000210132100004
