Multiplicity of Homoclinic Solutions for a Class of Nonperiodic Fourth-Order Differential Equations with General Perturbation

الملخص EN

In this paper, we investigate a class of nonperiodic fourth-order differential equations with general perturbation.

By using the mountain pass theorem and the Ekeland variational principle, we obtain that such equations possess two homoclinic solutions.

Recent results in the literature are generalized and significantly improved.
