摘要
通过非线性变换将爆炸解问题转化成等价的带奇异项的Dirichlet问题,并应用摄动方法,结合上下解方法与椭圆型方程的估计理论得到了爆炸解的存在性.
In this paper the nonlinear change of variable transforms the problem of explosive solutions into the equivalent Dirichlet problem with the singular term. It follows by the perturbed method,combining sub supersolutions method and the estimates theorey for elliptic equations of second order,the existence of explosive solutions is obtained.
