摘要 在Ω×[0,T)中考虑如下非线性Sine-Gordon方程初值问题解的爆破这里,Ω是R中具有光滑边界Ω的有界域。在Dirichlet边界条件下,得到了其解爆破的若干充分条件,然后通过能量方法,得到了解的生命跨度的上界估计。 Considered the blow up of the solution for the following nonlinear Sine-Gordon equation with the initial-boundary value in Ω×[O,T):Utt-uxx=-sin u,x∈Ω;u(x,O)=uo(x),x∈Ω;ut(x,O)=u1(x),x∈Ω.where Ω is a bounded field in R with sufficiently smooth boundary ,ЭΩ. Some sufficient conditions of the blow up of the solution are obtained under the dirichlet boundary. And then,based on the energy method,the super estimate of lifespan for these probllems is given.
