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 Aand deferred Ces\`{a}ro 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.
