能量临界离焦Hartree方程径向数据的整体适定性和离散性

Global well-posedness and scattering for the energy-critical, defocusing Hartree equation for radial data

Changxing Miao, Guixiang Xu, Lifeng Zhao

摘要:

我们考虑散焦,$\dot{H}^1$临界Hartree方程的径向数据在所有维度$(n\geq 5)$。我们在能量空间中证明了该模型的全局适定性和散射结果。本文的创新之处在于,我们首先利用定域Morawetz恒等式中的$\displaystyle - \int_{I}\int_{|x|\leq A|I|^{1/2}}|u|^{2}Δ\Big(\frac{1}{|x|}\Big)dxdt$项来排除能量集中的可能性,而不是依赖于非线性的经典Morawetz估计.

英文摘要:

We consider the defocusing, $\dot{H}^1$-critical Hartree equation for the radial data in all dimensions $(n\geq 5)$. We show the global well-posedness and scattering results in the energy space. The new ingredient in this paper is that we first take advantage of the term $\displaystyle - \int_{I}\int_{|x|\leq A|I|^{1/2}}|u|^{2}Δ\Big(\frac{1}{|x|}\Big)dxdt$ in the localized Morawetz identity to rule out the possibility of energy concentration, instead of the classical Morawetz estimate dependent of the nonlinearity.
