Abstract

When α ≥ 0 and Ω Lq(Sn−1) (q > 1), μΩ,α and τΩ,α can be defined by μΩ,α(f )(x) = (∫R2−2tα FΩ,t(f )(x)2dt) ½ and τΩ,α(f )(x) = ∫R 2−tαFΩ,t(f )(x)dt, where FΩ,t(f )(x) = 2−t 2t ∫0 b(s) ∫ Sn−1 Ω(y′)f (x − sy′)dσ(y′)ds. This paper gives the boundedness of μΩ,α and τΩ,α from the homogeneous weighted Sobolev space Lpα (w) to Lp(w), where p, q, and w satisfy certain conditions. Furthermore, this paper shows that the Marcinkiewicz integral operators μΩ,α,S and μ∗ Ω,α,λ are also bounded from Lpα (w) to Lp(w).
