Periodic Solutions of a Class of Perturbed Implicit Equations with Memory
摘要
We study the harmonic solutions of periodically perturbed implicit integrodifferential equations of a particular form obtaining, under appropriate topological conditions, a “branching-type” result for the nontrivial periodic solutions. The proof employs a combination of techniques from the theory of Topological Degree, Functional Differential Equations, and Differential-Algebraic Equations.
