双线性双参数奇异积分的交换子

Commutators of bilinear bi-parameter singular integrals

Kangwei Li, Henri Martikainen, Emil Vuorinen

摘要:

研究了由$b$和$T$构成的积分算子的有界性,其中$T$是满足自然$T1$型条件的双线性双参数奇异积分,$b$是小BMO函数.对于无副积的双线性双参数奇异积分$T$,证明了$[b, T]_1 \colon L^p(\mathbb{R}^{n+m}) \times L^q(\mathbb{R}^{n+m}) \to L^r(\mathbb{R}^{n+m})$在全值域$1 < p, q \le \infty$,$1/2 < r < \infty$满足$1/p+1/q = 1/r$ .特殊情况是当$T$是双线性双参数乘法器时。对于所有满足$T1$型条件的奇异积分,我们也证明了相应的Banach值域结果.在这样做时,我们简化了相应的线性证明。最后,我们证明了类似的结果,迭代迭代算子。

英文摘要:

We study the boundedness properties of commutators formed by $b$ and $T$, where $T$ is a bilinear bi-parameter singular integral satisfying natural $T1$ type conditions and $b$ is a little BMO function. For paraproduct free bilinear bi-parameter singular integrals $T$ we prove that $[b, T]_1 \colon L^p(\mathbb{R}^{n+m}) \times L^q(\mathbb{R}^{n+m}) \to L^r(\mathbb{R}^{n+m})$ in the full range $1 < p, q \le \infty$, $1/2 < r < \infty$ satisfying $1/p+1/q = 1/r$. A special case is when $T$ is a bilinear bi-parameter multiplier. We also prove the corresponding Banach range result for all singular integrals satisfying the $T1$ type conditions. In doing so we simplify the corresponding linear proof. Lastly, we prove analogous results for iterated commutators.
