Abstract
In this article, we discuss a type of second-order neutral differential equations with variable coefficient and delay:
where \(c(t)\in C({\mathbb {R}},{\mathbb {R}})\) and \(|c(t)|\ne 1\). By employing Krasnoselskii’s fixed-point theorem and properties of the neutral operator \((Ax)(t):=x(t)-c(t)x(t-\tau (t))\), some sufficient conditions for the existence of periodic solutions are established.
