Özet

In this paper, the necessary and sufficient conditions are found for the boundedness of the rough B-fractional interal operators from the Lorentz spaces L (P.s.gamma) to L (q ,r ,gamma) , 1 < p < q < infinity, 1 <= r <= s <= infinity, and from L-1 .r . gamma to L-q,L- infinity,L-gamma W L-q,L-gamma, 1 < q < infinity, 1 <= r <= infinity. As a consequence of this, the same results are given for the fractional B-maximal operator and B-Riesz potential. (c) 2007 Elsevier Inc. All rights reserved.
