| Description | The paper deals with the second order nonlinear differential equation in the case when the weight has indefinite sign. In particular, the problem of the existence of the so-called globally positive Kneser solutions on the whole half-line is considered. Moreover, conditions assuring that these solutions tend to zero are investigated by a Schauder's half-linearization device jointly with some properties of the principal solution of an associated half-linear differential equation. The results cover also the case in which the weight is a periodic function or it is unbounded from below. |
