On deferred statistical A-convergence of fuzzy sequence and applications

This paper introduces the idea of deferred-statistical A-convergence of order β of the sequence of fuzzy numbers by using a regular matrix A and deferred Cesiaro mean D_p,q. Also, we establish some relations between the proposed idea and the strong deferred A-summability of sequences of fuzzy numbers. As an application, we apply this newly statistical convergence for proving fuzzy Korovkin-type approximation theorem. Some illustrative examples are provided to justify the results obtained from this investigation.
