The Existence of Periodic Solutions of Delay Differential Equations by E+-Conley Index Theory
In this paper, the E+-Conley index theory has been used to study the existence of periodic solutions of nonautonomous delay differential equations (in short, DDEs). The variational structure for DDEs is built, and the existence of periodic solutions of DDEs is transferred to that of critical points...
