摘要 作者引入了非齐型空间上的弱Herz空间,并建立了一类次线性算子在这些空间中的弱型估计.作为应用,证明了由Calderón-Zygmund算子和Osc_(exp L^r)(μ)函数生成的交换子在弱Herz空间中的弱型估计,其中r≥1.并且Orlicz空间Osc_(exp L^r)(μ)当r=1时即为RBMO(μ)空间;当r>1时为RBMO(μ)的子空间. The authors introduce weak Herz spaces on non-homogeneous spaces some weak type estimates for a class of sublinear operators in these spaces and establish As an application, the authors prove that the commutators generated by Calderdn-Zygmund operators with OSCexpL^r(μ) functions for r 〉 1 satisfy the same weak estimates, where OSCexpL^r(μ) belong to RBMO(μ) if r 〉 1 and OscexpL^r(μ) = RBMO(μ) if r = 1.
