Variational Methods for Almost Periodic Solutions of a Class of Neutral Delay Equations

الملخص EN

We provide new variational settings to study the a.p.

(almost periodic) solutions of a class of nonlinear neutral delay equations.

We extend Shu and Xu (2006) variational setting for periodic solutions of nonlinear neutral delay equation to the almost periodic settings.

We obtain results on the structure of the set of the a.p.

solutions, results of existence of a.p.

solutions, results of existence of a.p.

solutions, and also a density result for the forced equations.
