Abstract

The \(\varphi \)-index of inclusion has proven to be a suitable generalization of the inclusion in the fuzzy setting. In this paper, the properties of the \(\varphi \)-index of inclusion, when its definition is restricted to a subset of indexes, are analyzed. The theoretical results obtained in this work are necessary in order to develop fuzzy inference systems based on the \(\varphi \)-index of inclusion.

Notes

  1. 1.

    Usually, in approaches related to measures of inclusion, e.g., [10], bijective mappings in \(\mathcal {U}\) are called transformations.

  2. 2.

    A pair of functions (fg) forms an isotone Galois Connection if the following holds: \(f(x)\le y\) if and only of \(x\le g(y)\), for all \(x,y\in [0,1]\).
