Fractional integral operators on Herz spaces for supercritical indices
We consider the boundedness of fractional integral operators Iβ on Herz spaces , where q ≥ n/β. We introduce a new function space that is a variant of Lipschitz space. Our results are optimal.

A note on multilinear fractional integrals
Shi and Tao[6] studied the boundedness of multilinear fractional integrals introduced by Kenig and Stein[3] on product of weighted L p -spaces, and got some results. We give some remarks with respect to their results and correct some mistakes. We also consider another multilinear fractional integral introduced by Grafakos[2].

Factorization of functions in H1(ℝn) and generalized Morrey spaces
We prove a factorization theorem for functions in H 1(ℝn ) using generalized Morrey spaces. As a corollary of our result we show that if the commutator of Coifman, Rochberg and Weiss [b , T ] is bounded on the generalized Morrey spaces, then b is a BMO function.

Weighted Estimates for Operators Generated by Maximal Functions on Nonhomogeneous Spaces
We consider weighted weak type estimates for the modified Hardy–Littlewood maximal functions on a nonhomogeneous space. We use the new covering lemma by Sawano.

Weak type estimates for Calderón‐Zygmund operators on Herz spaces at critical indexes
We define weak Herz spaces $ \dot K ^{\alpha , p, \infty} _{q} $(ℝn) which are the weak version of the ordinary Herz spaces $ \dot K ^{\alpha , p} _{q} $(ℝn). We consider the boundedness of Calderón‐Zygmund operators from $ \dot K ^{\alpha , p} _{q} $ to $ \dot K ^{\alpha , p, \infty} _{q} $ at critical indexes α = −n/q, n(1− 1/q) and q = 1. We also consider weighted estimates.- 11 September 2003
