Kyouhei Wakasa

摘要:

本文考虑一维空间中带加权非线性项的非线性波动方程的初值问题。Kubo & Osaka & Yazici(2013)研究了在不同的非线性和初始数据条件下问题的全局可解性,以及问题寿命的上界。本文的目的是改进生命周期的上界,并导出其下界,证明新的上界是最优的。

英文摘要:

In this paper, we consider the initial value problem for nonlinear wave equation with weighted nonlinear terms in one space dimension. Kubo & Osaka & Yazici(2013) studied global solvability of the problem under different conditions on the nonlinearity and initial data, together with an upper bound of the lifespan for the problem. The aim of this paper is to improve the upper bound of the lifespan and to derive its lower bound which shows the optimality of our new upper bound.
