Using inequality techniques and coincidence degree theory, new results are provided concerning the existence of \(T\)-periodic solutions for fourth-order nonlinear differential equations. Two illustrative examples are provided to demonstrate that the results in this paper hold under weaker conditions than the existing ones, and are more effective.
