A common fixed point theorem in fuzzy metric spaces. (English) Zbl 0867.54017
Summary: In this note Jungck’s common fixed point theorem is generalized to fuzzy metric spaces. M. Grabiec [Fuzzy Sets Syst. 27, 385-389 (1988; Zbl 0664.54032)] proved the contraction principle in the setting of fuzzy metric spaces introduced by I. Kramosil and J. Michálek [Kybernetica, Praha 11, 336-344 (1975; Zbl 0319.54002)]. This note offers a generalization of G. Jungck’s theorem [Am. Math. Mon. 83, 261-263 (1976; Zbl 0321.54025)] in the setting of a fuzzy metric space.
