Abstract. In a recent article [Mathematics (2024), 2024:305] it was shown that the renowned Suzuki fixed point theorem [Proc. Amer. Math. Soc. 136 (2008), 1861–1869] cannot be generalized in an obvious and natural way to the setting of w-distances. In contrast to this situation, we here show that our fuzzy counterpart of Suzuki’s theorem [J. Nonlinear Convex Anal. 23 (2024), 1487-1494] admits a full generalization to the framework of fuzzy w-distances.

Keywords: fixed point; fuzzy metric space; fuzzy w-distance; w-Suzuki fuzzy contraction
