外部区域中的弹性波,第II部分:具有零结构的整体存在性

Elastic waves in exterior domains, Part II: Global existence with a null structure

Jason Metcalfe, Becca Thomases

摘要:

在这篇文章中,我们证明了一个小的初始位移对应的非线性弹性问题的解存在于一个非陷阱障碍物的外部的整体。介质被假定为均匀的,各向同性的,和超弹性的,和非线性被假定为满足零条件。本文所包含的技术将允许更复杂的几何形状,只要对于线性化问题存在足够的局部能量衰减。

英文摘要:

In this article, we prove that solutions to a problem in nonlinear elasticity corresponding to small initial displacements exist globally in the exterior of a nontrapping obstacle. The medium is assumed to be homogeneous, isotropic, and hyperelastic, and the nonlinearity is assumed to satisfy a null condition. The techniques contained herein would allow for more complicated geometries provided that there is a sufficient decay of local energy for the linearized problem.
