New Hermite–Hadamard-type inequalities for "Equation missing" <!-- No EquationSource Format="TEX", only image -->-convex fuzzy-interval-valued functions

Abstract In this paper, we introduce the non-convex interval-valued functions for fuzzy-interval-valued functions, which are called "Equation missing"-convex by means of fuzzy order relation. This relation is defined level-wise through Kulisch–Miranker given on interval space. By using -->-convexity concept, present fuzzy-interval Hermite–Hadamard inequalities functions. Several exceptional cases debated, can be viewed as useful applications. Interesting examples that verify applicability theory developed in study presented. The results paper considered extensions previously established results.
