In this paper, we introduce a new type of almost statistical convergence of generalized difference sequences of fuzzy numbers. We give the relations between the strongly almost Cesàro type convergence and almost statistical convergence in these spaces . Furthermore, we study some of their properties like completeness, solidity, symmetricity etc. We also give some inclusion relations related to ...

Our primary interest in the present paper is to prove a Korovkintype approximation theorem for n−multiple sequences of fuzzy positive linear operators via statistical convergence. Also, we display an example such that our method of convergence is stronger than the usual convergence. Mathematics Subject Classification (2010): 26E50, 40G15, 41A36.
