新的齐型BMO, Lipschitz空间上的奇异积分算子

Let(X, d, μ) be a space of homogeneous type, BMO_A(X) and Lip_A(β,X) be the space of BMO type,lipschitz type associated with an approximation to the identity {A_t}_t0 and introduced by Duong,Yan and Tang, respectively. Assuming that T is a bounded linear operator on L~2(X), we find the sufficient condition on the kernel of T so that T is bounded from BMO(X) to BMO_A(X) and from Lip(β, X) to Lip_A(β, X). As an application, the boundedness of Calderón-Zygmund operators with nonsmooth kernels on BMO(R~n) and Lip(β, R~n) are also obtained.     

齐型空间上的加权 H~p(ω)和对偶

设 X 是一个齐型空间,R.R.Coifman 和 G.Weiss 在[1]中定义 H~(p,q)(X)为 Lipschitz 空间(?)_α(α=1/p-1)的对偶空间(?)_α~*的子空间,且每个元素有原子分解.对带权ω情形,用什么空间去代替与 q 无关的(?)_α?本文首先证明了带权ω的 Campanto 空间的一个重要性质以 ∧_(p,q)(ω)=∧_(p,q_1)(ω)(0r_0),由此我们给出了 H~p(ω)的定义;最后证明了 H~p(ω)的对偶是带权ω的 Campanto 空间 ∧_p(ω).
