An oscillation theorem for higher order nonhomogeneous superlinear differential equations.
Global attractivity in a higher order nonlinear difference equation.
Classifications and existence of nonoscillatory solutions of second order nonlinear neutral differential equations
A class of neutral nonlinear differential equations is studied. Various classifications of their eventually positive solutions are given. Necessary and/or sufficient conditions are then derived for the existence of these eventually positive solutions. The derivations are based on two fixed point theorems as well as the method of successive approximations.
