Partial stability investigations of differential equations of second order (Q802836)

The author studies a class of second order differential equations of the form \(y''+p(t,y,y')y'+q(t,y,y')y=f(t,y,y')\) and derives estimates for the asymptotic behavior as \(t\to \infty\) of \(| y(t)|\) and \(| y'(t)|\).
