Common fixed point theorems for fuzzy mappings in quasi-pseudo-metric spaces. (English) Zbl 1075.54018

The main result is a fixed point theorem for a pair of fuzzy mappings on a left \(K\)-sequentially complete quasi-pseudo-metric space. Some results of V. Gregori and J. Pastor [Rend. Ist. Mat. Univ. Trieste 30, Suppl., 103–109 (1999; Zbl 0935.54032)], the third and first authors [J. Fuzzy Math. 10, No. 1, 105–110 (2002; Zbl 1010.54045)] and others are discussed as special cases.
