This paper is devoted to the study on disconjugacy criteria for a linear third order differential equation. We prove that the given equation has two linearly independent solution and discuss its disconjugacy.
Our method consists of reducing the equation to a non-linear second order equation by the substitution and using results concerning the existence of solutions for boundary-value problems for second order equations.
