    There are more discussion which concern nonlinear differential  equation in [13]

Abstract:

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.

Key words: Blow-up, Life-span, Blow-up constant, asymptotic behavior, null
