In this paper the quantum Hahn difference operator and the quantum Hahn integral operator are defined via the quantum shift operator θnew fractional integral inequalities are established by using the quantum Hahn integral for one and two functions bounded by quantum integrable functions. The Hermite-Hadamard type of ordinary and fractional quantum Hahn integral inequalities as well as the Pólya-Szegö type fractional Hahn integral inequalities and the Grüss-Cebyšev type fractional Hahn integral inequality are also presented.

The Hahn difference operator D q,ω , introduced in [1], is defined as D q,ω f (t) = ⎧ ⎨ ⎩ f (qt+ω)-f (t) t(q-1)+ω , t = ω 0 , f (ω 0 ), t = ω 0 ,
