设μ是Rd上的非负Radon测度,且满足增长性条件:存在一正常数Co,使得对任意的x∈Rd和r>0,有μ(B(x,r))≤C0rn,其中0<n≤d.该文研究了相关于非双倍测度μ的Marcinkiewicz积分与RBMO函数生成的交换子,得到了这类交换子的加Aρp(μ)权的弱型估计.
Let μ be a nonnegative Radon measure on R^d which only satisfies μ(B(x, r)) 〈 Cot^n for all x ∈ R^d, r 〉 0, n ∈ (0, d) and some fixed constants Co 〉 0. In this paper, a weak type estimate with Ap^p(μ) weight is established for commutators generated by Marcinkiewicz integrals operators with RBMO functions.
