Bilinear Operator and the Decomposition of $H^{1} imes BMO$
首发时间:2015-12-08
Abstract:In this paper, we prove that, for every $bin BMO(R^{n})$ and $finH^{1}(R^{n})$, by use of a kind of compensated quantities, we canget a decomposition of the product space $BMO(R^{n}) imesH^{1}(R^{n})$. Precisely, we obtain, for $fin H^{1}(R^{n})$, $binBMO(R^{n})$, the point-wise product $bcdot f$ as a Schwartzdistribution, denoted by $b imes fin S'(R^{n})$, can be decomposedinto two parts associated with the bilinear operators, that is$b imes f=u+v$, where $uin L^{1}(R^{n})$ and $v$ belongs to theHardy-Orlicz space $H^{mathcal{P}}(R^{n})$.

双线性算子和$H^{1} imes BMO$的分解
摘要:本文中, 我们证明, 对每个$bin BMO(R^{n})$ 和 $finH^{1}(R^{n})$, 利用一类补偿量, 我们可以得到乘积空间 $BMO(R^{n}) imesH^{1}(R^{n})$的分解.
