具有俘获和复位势的wave equation的衰变估计

A decay estimate for a wave equation with trapping and a complex potential

Lars Andersson, Pieter Blue, Jean-Philippe Nicolas

摘要:

在这篇短文中,我们考虑一个既有俘获势又有复位势的波动方程。对于这个问题,我们证明了一个统一的约束的能量和Morawetz(或综合当地的能量衰减)估计。该方程是一个模型问题的某些标量方程出现在麦克斯韦和线性化爱因斯坦系统的外部旋转黑洞。

英文摘要:

In this brief note, we consider a wave equation that has both trapping and a complex potential. For this problem, we prove a uniform bound on the energy and a Morawetz (or integrated local energy decay) estimate. The equation is a model problem for certain scalar equations appearing in the Maxwell and linearised Einstein systems on the exterior of a rotating black hole.
