摘要

In this paper the boundedness of the weighted iterated Hardy-type operators T_(u,b) and T_(u,b)* involving suprema from weighted Lebesgue space L_p(v) into weighted Cesaro function spaces Ces_q(w,a) are characterized. These results allow us to obtain the characterization of the boundedness of the supremal operator R_u from L~p(v) into Ces_q(w,a) on the cone of monotone non-increasing functions. For the convenience of the reader, we formulate the statement on the boundedness of the weighted Hardy operator P_(u,b) from L~p(v) into Ces_q(w,a) on the cone of monotone non-increasing functions. Under additional condition on u and b, we are able to characterize the boundedness of weighted iterated Hardy-type operator T_(u,b), involving suprema from L~p{v) into Ces_q(w,a) on the cone of monotone non-increasing functions. At the end of the paper, as an application of obtained results, we calculate the norm of the fractional maximal function M_y from Λ~P(v) into Γ~q(w).
