Abstract

Fu and Lu et al. 7 showed that the commutator \documentclass{article}\usepackage{amssymb}\begin{document}\pagestyle{empty}$\mathcal {H}_{\beta ,b}$\end{document} generated by the fractional Hardy operator and a locally integrable function b is bounded on the homogenous Herz spaces if and only if b is a central bounded mean oscillation function. We show that their result is optimal by giving a counterexample.

## Abstract Let__H~a,b~__ be the commutator generated by the generalized Hardy operator and the CMO function. The (__L^p^, L^p^__) boundedness of __H~a,b~__ is discussed in this paper. Furthermore, the authors consider the boundedness of __H~a,b~__ on the weighted homogeneous Herz spaces (Β© 2009 WI

## Abstract The aim of this note is to show how all the commutator estimates of two recent papers, by M. Cwikel, N. Kalton, M. Milman, and R. Rochberg and by N. Krugljak and M.

A sufficient condition is found for the product of two Toeplitz operators on the Hardy space of the unit sphere to be a compact perturbation of a Toeplitz operator. The condition leads to a criterion for a Hankel operator to be compact. ## 1997 Academic Press The object of this present paper is to
