title: On some Hermite-Hadamard type inequalities for (s, QC)-convex functions.
abstract: In the paper, the authors introduce a new notion "[Formula: see text]-convex function on the co-ordinates" and establish some Hermite-Hadamard type integral inequalities for [Formula: see text]-convex functions on the co-ordinates.
