In this paper we establish some oscillation or nonoscillation criteria for the second order half-linear differential equation
where
(i) r,c ∈ C([t
0, ∞), ℝ := (− ∞, ∞)) and r(t) > 0 on [t
0, ∞) for some t
0 ⩾ 0;
(ii) Φ(u) = |u|p−2
u for some fixed number p > 1.
We also generalize some results of Hille-Wintner, Leighton and Willet. 相似文献

This paper treats the rich mathematical structure of the (dimensionless) equation of motion governing the behavior of an elastically
restrained simple pendulum subject to a downward force of magnitude f(t) applied to its bob with $\dot{f}(t)>0$\dot{f}(t)>0 for all t>0 and f(t)→∞ as t→∞:

We establish asymptotic formulas for nonoscillatory solutions of a special conditionally oscillatory half-linear second order
differential equation, which is seen as a perturbation of a general nonoscillatory half-linear differential equation
