Statistical weighted mean summability of double sequences of fuzzy numbers


Özer Talo, Aslıhan Şen, Hüsamettin Çoşkun




In this paper, we present statistical weighted mean ( briefly, (N, p, q, 1, 1)) summability method for double sequences of fuzzy numbers and give necessary and sufficient Tauberian conditions under which statistical convergence of a double sequence of fuzzy numbers follows from its statistical (N, p, q, 1, 1) summability. Furthermore, we apply our new method of summability to prove a fuzzy Korovkin type approximation theorem for a double sequence of fuzzy positive linear operators
