摘要
将一类奇异非线性椭圆型方程正整解存在性问题转化为常微分方程初值问题 ,利用Schauder不动点定理证明了一类奇异非线性椭圆方程在R2 上的正整解的存在性 。
Turning problem of the existence of positive entire solutions for a singular nonlinear elliptic equation into original value for ordinary differential equation. The existence of positive entire solutions is tablished by utilizing the Schauder fixed point therom. It extends and improves present results.
