Asymptotic behavior of positive solutions of the nonlinear differential equation \(t^2u''=u^n\)
Electronic journal of differential equations, Tome 2013 (2013)
In this article we study properties of positive solutions of the ordinary differential equation $t^2u''=u^n$ for $1$, we obtain conditions for their blow-up in finite time, and some properties for global solutions. Equations containing more general nonlinear terms are also considered.
