摘要:

研究一维空间中带空间权的半线性波动方程的初值问题。在多项式权的所有情形下,建立了紧支数据下经典解的寿命估计。根据初速度的全积分,将结果分为两种情况。

英文摘要:

This paper studies initial value problems for semilinear wave equations with spatial weights in one space dimension. The lifespan estimates of classical solutions for compactly supported data are established in all the cases of polynomial weights. The results are classified into two cases according to the total integral of the initial speed.
