二階非線性微分方程解的行為 / On the behavior of solution for non-linear differential equation

陳盈潤 Unknown Date (has links)
在這篇論文,我們考慮半線性微分方程式的初始邊界值問題之解u,的存在性,唯一性,和他的行為. (i) t^{-sigma}u''(t)=r_1u(t)^p+r_2u(t)^p(u'(t))^2, u(1)=u_0,u'(1)=u_1, 其中 p>1 為常數. 對t≥1,sigma>0,p>1 為偶數,r_1>0,r_2>0,u_0>0,u_1>0. 我們得到以下的結果.
解的爆炸時間
解的最大存在時間
Emden-Fowler方程式
Blow up time for solution
The lift-span for solution
Emden-Fowler equation
