Summary: This paper is concerned with a second-order function differential equation. By constructing a convergent power series solution of an auxiliary equation, analytic solutions for the original differential equation are obtained. We discuss not only those $α$ is a root of unity but also those $α$ near resonance under Brjuno condition.
