Abstract: We consider the half-linear second order differential equation which is viewed as a perturbation of the so-called Riemann-Weber half-linear differential equation. We present a comparison theorem with respect to the power of the half-linearity in the equation under consideration. Our research is motivated by the recent results published by J. Sugie, N. Yamaoka, Acta Math. Hungar. 111 (2006), 165-179.
Keywords: Riemann-Weber half-linear equation, Riccati technique, power comparison theorem, perturbation principle, principal solution
