The Hardy–Littlewood–Sobolev theorem for Riesz potential generated by Gegenbauer operator

In this paper we introduced and studied the maximal function (GG-maximal function) and the Riesz potential (GG-Riesz potential) generated by Gegenbauer differential operator Gλ=(x2−1)12−λddx(x2−1)λ+12ddx. The Lp,λLp,λ boundedness of the GG-maximal operator is obtained. Hardy–Littlewood–Sobolev theorem of GG-Riesz potential on Lp,λLp,λ spaces is established.
