In this work, the authors introduce the notion of harmonically subadditive functions. We establish inequalities of Hermite-Hadamard and Fejer type for newly defined classes of functions via ordinary and Riemann-Louville fractional integrals. The results presented in this work are the refinements of several existing results. The results of this paper may stimulate further research for the researchers working in this field.
