Comparison Theorems for Pseudoconjugate Points of Half-linear Ordinary Differential Equations of the Second Order
K. Rostas


Abstract.  This paper generalizes well known comparison theorems for linear differential equations of the second order to half-linear differential equations of second order. We are concerned with pseudoconjugate and deconjugate points of solutions of these equations.
