Some new generalized κ–fractional Hermite–Hadamard–Mercer type integral inequalities and their applications

AIMS Mathematics, 2022
In this paper, we have established some new Hermite–Hadamard–Mercer type of inequalities by using κ–Riemann–Liouville fractional integrals. Moreover, we have derived two new integral identities as auxiliary results.
