    The paper deals with the asymptotic form of three linearly independent solutions of the third-order differential equation \((q(qy')')'+py'+ry=0\) as \(x\to \infty\) where \(q\neq 0\) in some interval [a,\(\infty)\). The critical (Euler) case is identified in terms of some relation between q and r and analyzed separately.
