Common fixed points of four mappings in a fuzzy metric space. (English) Zbl 1022.54004

Using the definition of fuzzy metric spaces by A. George and P. Veeramani [Fuzzy Sets Syst. 64, 395-399 (1994; Zbl 0843.54014)], the authors give the existence of a contractive definition which generates a fixed point but does not force the mapping to be continuous at the fixed point in the setting of fuzzy sets.
