We also establish Hermite-Hadamard and some related inequalities for co-ordinated convex interval-valued functions by applying the newly defined fractional integrals. The results of the present paper are the extension of several previously published results. © 2021 Huseyin Budak et al., published by De Gruyter.en10.1515/math-2021-0067info:eu-repo/semantics/openAccessfractional integralsHermite-Hadamard inequalityinterval-valued functionsFractional Hermite-Hadamard-type inequalities for interval-valued co-ordinated convex functionsArticle191108110972-s2.0-85117069629WOS:000731751300001Q3Q2
