Common fixed points of compatible maps in fuzzy metric spaces (Q1591015)

Several researchers have defined the concept of fuzzy metric space in various ways. In this paper, the authors introduce the concept of compatibility on fuzzy metric space (in the sense of a definition given in [\textit{A. George} and the reviewer, ibid. 64, No. 3, 395-399 (1994; Zbl 0843.54014)] and use it to prove common fixed point theorems for compatible mappings. It should be noted that the authors prove two common fixed point theorems for a fuzzy metric space having continuous \(t\)-norm defined by \(a^*b= \min\{a,b\}\), \(a,b\in [0,1]\). The authors do not discuss their results for an arbitrary continuous \(t\)-norm. It is of worth to investigate whether the fixed point theorems proved in this paper are true for arbitrary \(t\)-norms.
