Fractional derivatives of the products of Airy functions are investigated, D α {Ai 2 (x)} and D α {Ai(x) × Bi(x)}, where Ai(x) and Bi(x) are the Airy functions of the first and second type, respectively. They turn out to be linear combinations of D α {Ai(x)} and D α {Gi(x)}, where Gi(x) is the Scorer function. It is also proved that the Wronskian W(x) of the system of half integrals {D −1/2 Ai(x), D −1/2 Gi(x)} and its Hilbert transform W(x) = −H W(x) can be considered special functions in their own right since they are expressed in terms of Ai 2 (x) and Ai(x)Bi(x), respectively. Various integral relations are established. Integral representations for D α {Ai(x − a)Ai(x + a)} and its Hilbert transform −H D α {Ai(x − a)Ai(x + a)} are derived.
