摘要:
研究具非线性耗散项的p-方程组的初值问题.在非线性耗散项较弱的假设条件下,解除了对初值的C1-模的小性限制.即对初值的C0-模不加小性限制,而需其一阶导数的C0-模足够小.运用经典的特征线法和极值原理,分别得到解的C0-模估计和偏导数的C0-模估计.根据光滑解的局部存在性定理和先验估计的结果,利用逐步延拓法,证明初值问题的整体光滑解的唯一存在性.
Abstract:
We consider the initial value problem for the nonlinear damped p-system.We prove thatit doesn′t require that the C0-norm of the initial data is small,while it just needs the C0-norm of the first order derivative to be sufficiently small.Utilizing some priori estimate,we prove he existences of the global smooth solution for the initial value problem.In order to get a priori estimate of the solutions,by the classical characteristic method,which is used to get the priori C0-norm estimate on the solutions,and by applying the maximum principle,we get uniformly estimates on the derivatives of the solutions with respect to x.
