摘要：
By this work, our aim is to study oscillatory behaviour of solutions to 4th-order differential equation of neutral type L-y' + Sigma(k)(j-1) q(j)(y)z(beta)(g(j)(y)) = 0 where L-y = xi(y)(w'"(y))(alpha), w(y): = z(y) + r(y)z((g) over tilde (y)). By using the comparison method with first-order differential inequality, we find new oscillation conditions for this equation.
