Electronic Journal of Differential Equations, Conference 03 (1999), pp. 29-37. Title: A remark on the half-linear extension of the Hartman-Wintner theorem Author: Ondrej Dosly (Czech Academy of Sciences, Czech Republic) Abstract: We establish a Hartman-Wintner type theorem for the half-linear second order differential equation $$ (r(t)\Phi_p(x'))'+c(t)\Phi_p(x)=0,\quad \Phi_p(x):=|x|^{p-2}x.$$ This equation is viewed as a perturbation of the non-oscillatory equation $$ (r(t)\Phi_p(x'))'+\tilde c(t)\Phi_p(x)=0 $$ with $\tilde c(t)\ne 0$ eventually.
