Abstract

In this paper, the notion of fuzzy feebly $F_\sigma$-complemented space is introduced and several characterizations of fuzzy feebly $F_\sigma$-complemented spaces are established. The inter-relations between weakly $F_\sigma$-complemented spaces and fuzzy feebly $F_\sigma$-complemented spaces are established. The conditions, under which fuzzy feebly $F_\sigma$-complemented spaces become fuzzy $F$-spaces and fuzzy $F^{\prime}$-spaces become fuzzy normal spaces, are also obtained in this paper.
