The Existence of Nonoscillatory Solutions to Higher Order Nonlinear Neutral Differential Equations
It studies the existence of nonoscillatory solutions of variable coefficient higher order nonlinear neutral differential equations by the Banach contraction principle. Some new sufficient conditions have been obtained
