微分算子在$\mathbb{R}^2$中的双线性嵌入定理

Bilinear embedding theorems for differential operators in $\mathbb{R}^2$

Dmitriy M. Stolyarov

摘要:

证明了$\mathbb{R}^2$中微分算子的双线性不等式.这类不等式在超定组的各向异性嵌入定理和极限阶和指数等方面都是有用的。在这里,我们研究的是现象本身。我们考虑椭圆的情况下,我们的分析是完整的,和非椭圆的,它不是。后一种情况与二维情形下的Eschenhartz估计有关。

英文摘要:

We prove bilinear inequalities for differential operators in $\mathbb{R}^2$. Such type inequalities turned out to be useful for anisotropic embedding theorems for overdetermined systems and the limiting order summation exponent. However, here we study the phenomenon in itself. We consider elliptic case, where our analysis is complete, and non-elliptic, where it is not. The latter case is related to Strichartz estimates in a very easy case of two dimensions.
