超临界Wave Equations的大型外输解决方案

Large Outgoing Solutions to Supercritical Wave Equations

Marius Beceanu, Avy Soffer

摘要:

对一类径向对称的有限能量初值,证明了R^{3+1} u_{tt} -Δu + |u| ^N u = 0,u(0)= u_0,ut(0)= u_1,4<N< \infty中能量超临界波动方程整体解的存在性.该类中的函数在线性流下被描述为是传出的-对于下面定义的“传出”的特定含义。特别是,我们构造的初始数据与大(甚至无限)的关键Sobolev,Besov,Lebesgue,洛伦兹规范和其他几个大的关键规范的全球解决方案。

英文摘要:

We prove the existence of global solutions to the energy-supercritical wave equation in R^{3+1} u_{tt}-Δu + |u|^N u = 0, u(0) = u_0, u_t(0) = u_1, 4<N<\infty, for a large class of radially symmetric finite-energy initial data. Functions in this class are characterized as being outgoing under the linear flow --- for a specific meaning of "outgoing" defined below. In particular, we construct global solutions for initial data with large (even infinite) critical Sobolev, Besov, Lebesgue, and Lorentz norms and several other large critical norms.
