In this article, we study the following initial value problem for the nonlinear equation
{u″u(t)=c1+c2u′(t)^2, c1≥0, c2≥0,
u(0)=u0, u′(0)=u1.
We are interested in properties of solutions of the above problem. We find the life-span, blow-up rate, blow-up constant and the regularity, null point, critical point, and asymptotic behavior at infinity of the solutions. 相似文献
