COMMUTATORS OF SINGULAR INTEGRAL OPERATORS WITH NON-SMOOTH KERNELS

Abstract

Abstract:

Let $T$ be a singular integral operator
bounded on $L^p({{\bf R}^n})$ for some $p$, $1 The authors give
a sufficient condition on the kernel of
$T$ so that when $b\in $BMO, the commutator
$[b, T](f)=T(b f)-b T(f)
$ is bounded on the space $L^p$ for all $p, 1 The condition of this paper is weaker than the usual pointwise
H\"ormander condition.

Key words: Commutator, BMO;singular integrals;semigroup kernel
