摘要
该文研究一类非线性高阶波动方程u_(tt)-a_1u_(xx)+a_2u_(x^4)+a_3u_(x^4_(tt))=ф(u_x)_x+f(u,u_x,u_(xx)u_(xxx),u_(x^4))的初边值问题.证明整体古典解的存在唯一性并给出古典解爆破的充分条件.
In this paper the initial boundary value problems for a class of nonlinear wave equation utt-a1uxx+a2ux4+a3ux4tt)=ф(ux)x+f(u,ux,uxxuxxx,ux4)are considered. The existence and uniqueness of the classical global solution are proved. The sufficient conditions of blow-up of solutions are given.
