Abstract: In this paper, we prove fixed points for hybrid pairs of L -fuzzy and non-self mappings in non-Archimedean L -fuzzy metric spaces. First, we define the notion of joint common limit range property ((JCLR) property) in such spaces. Further, we prove some common fixed point theorems for L -fuzzy and non-self mappings in non-Archimedean L -fuzzy metric spaces. Also, an integral contractive condition and implicit relation have been used in some results. These theorems extend, generalize and improve corresponding previous results in metric, fuzzy metric and L -fuzzy metric spaces.

Keywords: ℒ–Fuzzy metric spaces, ℒ–fuzzy mappings, (JCLR) property, common fixed point
