基于Calderon-Zygmund分解的非倍测度奇异积分弱(1,1)不等式的证明

A proof of the weak (1,1) inequality for singular integrals with non doubling measures based on a Calderon-Zygmund decomposition

Xavier Tolsa

摘要:

给定$R^d$上的一个加倍测度$μ$,调和分析的一个经典结果是:在$L^2(μ)$中有界的Calderon-Zygmund算子也是弱型(1,1).最近已经表明,如果用$μ$上的温和增长条件代替$μ$上的加倍条件,同样的结果也成立。本文给出了这个结果的另一种证明。证明是非常接近的精神,以经典的论点加倍措施,它是基于一个新的Calderon-Zygmund分解适应非加倍的情况。

英文摘要:

Given a doubling measure $μ$ on $R^d$, it is a classical result of harmonic analysis that Calderon-Zygmund operators which are bounded in $L^2(μ)$ are also of weak type (1,1). Recently it has been shown that the same result holds if one substitutes the doubling condition on $μ$ by a mild growth condition on $μ$. In this paper another proof of this result is given. The proof is very close in spirit to the classical argument for doubling measures and it is based on a new Calderon-Zygmund decomposition adapted to the non doubling situation.
