Deferred Cesàro means of fuzzy number-valued sequences with applications to Tauberian theorems

Abstract

In this paper, the deferred Ces?ro means of fuzzy number-valued sequences are studied and their summability by the deferred Ces?ro method with respect to the supremum metric is introduced. Also, Tauberian conditions to retrieve the convergence of a fuzzy number-valued sequence from its deferred Ces?ro summability are investigated.
