In the paper we study the weighted (L-p,(omega),(lambda), L-q,L-omega,L-lambda)-boundedness of the fractional maximal operator Mb' (G is a fractional maximal operator) and the Riesz potential (G is the Riesz potential) generated by the Gegenbauer differential operator G(lambda ) G = (x(2) - 1)(1/2-lambda )d/dx (x(2) - 1)(lambda+1/2 )d/dx, x is an element of (1,infinity), lambda is an element of (0,1/2).
