Comment on “Corrigendum to ‘On Interval-Valued Hesitant Fuzzy Soft Sets’” and “Generalized Trapezoidal Fuzzy Soft Set and Its Application in Medical Diagnosis”

Abstract EN

The aim of this article is to correct assertions (3) and (4) of Theorem 17 proposed by Khalil et al.

[1] and assertions (3) and (4) of Theorem 29 proposed by Zhang et al.

[2].

We first generalize (in an unambiguous manner) the fitting or remedy of the involved preliminary notions concerning interval-valued hesitant fuzzy soft set and generalized trapezoidal fuzzy soft sets and then use these notions to remedy the flaw in those assertions.
