关于一维波动方程的导数半线性模型经典解存在性的注记

Note on the existence of classical solutions of derivative semilinear models for one dimensional wave equation

Yuki Haruyama, Takiko Sasaki, Hiroyuki Takamura

AI总结:

本文补充了Takamura关于一维非线性波动方程的综述,研究具有乘积型导数非线性项的半线性波动方程经典解的长时间存在性,通过逐点估计的经典迭代论证扩展了单分量情形,为验证一般理论的最优性提供了更多模型。

摘要:

本文是对Takamura [13]关于一维空间中非线性波动方程综述论文的补充,提供了一个新结果。我们在此关注一维空间中半线性波动方程经典解的长时间存在性,特别是具有乘积型导数非线性项的情况。我们的结果是单分量情形的扩展,但提供尽可能多的模型以涵盖一般理论的最优性是有意义的。证明基于解的逐点估计的经典迭代论证。

英文摘要:

This note is a supplement with a new result to the review paper by Takamura [13] on nonlinear wave equations in one space dimension. We are focusing here to the long-time existence of classical solutions of semilinear wave equations in one space dimension, especially with derivative nonlinear terms of product-type. Our result is an extension of the single component case, but it is meaningful to provide models as possible as many to cover the optimality of the general theory. The proof is based on the classical iteration argument of the point-wise estimate of the solution.
