Sun, Yong Zhong et Su, Wei Yi, An Endpoint Estimate for the Commutator of Singular Integrals, Acta mathematica Sinica. English series (Print) , 21(6), 2005, pp. 1249-1258
It is well known that the commutator T b of the singular integral operator T with a BMO function b is bounded on L p(R n), 1 < p < .. In this paper, we consider the endpoint estimates for a kind of commutator of singular integrals. A BMO.type estimate for T b is obtained under the assumption b . LMO.
