The partial order N_b- fuzzy metric space and fuzzy coupled coincidence fixed point theorem

Abstract

In the present paper, we prove fuzzy coupled coincidence fixed point theorem in the structure of symmetric partial order N_b-fuzzy metric space. Our results extend and generalize the results of Wang et al. [15] and Tenguria J. et al. [14] in the setting of symmetric partial order N_b-fuzzy metric space. Finally, one example is also given to illustrate the main result of this paper.
