Abstract

Associativity of a two-place function T:[0,1]2[0,1]T: [0,1]^2\rightarrow [0,1] defined by T(x,y)=f(1)(T(f(x),f(y)))T(x,y)=f^{(-1)}(T^*(f(x),f(y))) where T:[0,1]2[0,1]T^*:[0,1]^2\rightarrow[0,1] is an associative function with neutral element in [0,1][0,1], f:[0,1][0,1]f: [0,1]\rightarrow [0,1] is a monotone right continuous function and f(1):[0,1][0,1]f^{(-1)}:[0,1]\rightarrow[0,1] is the pseudo-inverse of ff depends only on properties of the range of ff. The necessary and sufficient conditions for the TT to be associative are presented by applying the properties of the monotone right continuous function ff.
