Associativity of discretized triangular norms

Di Zhang, Xue-ping Wang

In this article, we mainly investigate when the binary operation $T^{[n]} : [0, 1]^{2} \to [0, 1]$ satisfies the associative law and thus becomes a triangular norm where \begin{…

Bounds of triangular subnorms and their algorithms

Ting Tang, Xue-ping Wang

This article deals with the upper and lower bounds of triangular subnorms generated by continuous, strictly decreasing additive generators. It first establishes necessary and suffi…

Monotone functions that generate conditionally cancellative triangular subnorms

Meng Chen, Xue-ping Wang

Let a function $F : [0, 1]^{2} \to [0, 1]$ be given by $F (x, y) = f^{(- 1)} (T (f (x), f (y)))$ where $f : [0, 1] \to [0, 1]$ is a monotone function, $f^{(- 1)}$ is the pseudo-invers…

A characterization of a class of border continuous triangular conorms

Zhi-qiang Lai, Xue-ping Wang

Let $T^{*} : [0, 1]^{2} \to [0, 1]$ be a continuous, non-decreasing and associative function with neutral element, $f : [0, 1] \to [0, 1]$ be a strictly monotone function and $f^…

Associativity of two-place functions generated by left continuous monotone functions and other properties

Meng Chen, Xue-ping Wang

This article introduces a weak pseudo-inverse of a monotone function, which is applied to characterize the associativity of a two-place function $T : [0, 1]^{2} \to [0, 1]$ defin…

Associativity of a class of two-place functions and its consequences for classes of triangular norms

Yun-Mao Zhang, Xue-ping Wang

This article characterizes the associativity of two-place functions $T : [0, 1]^{2} \to [0, 1]$ defined by $T (x, y) = f^{(- 1)} (F (f (x), f (y)))$ where $F : [0, 1]^{2} \to [0, 1]$ is a…
