一个常微分方程整体解的存在性结果
An existence result of an ordinary differential equation
摘要
研究常微分方程(d^2u)/(dx^2)+K(x)e^(2u)=0在(-∞,+∞)上整体解的存在性问题.此方程是熟知的在R^2上预定高斯曲率方程的一个特例.本文证明了一个存在性定理.
This paper studies the existence problem of the ordinary differential equation d^2u/dx^2+K(x)e^2u=0 on R. This equation is a special case of the so called prescribing Gaussian curvature problem on R^2. An existence result is proved.
