Inclusion theorems for (C,k) summability method of sequences of fuzzy numbers

Abstract

We introduce (C,k) summability method of sequences of fuzzy numbers and compare (C,k) summability method with Abel summability method, Holder summability method and with higher order Cesaro method of sequences of fuzzy numbers. Some Tauberian conditions under which (C,k) summability of sequences of fuzzy numbers imply convergence in fuzzy number space are also obtained as corollaries.
