Existence and Uniqueness of Periodic Solutions of Mixed Monotone Functional Differential Equations

This paper deals with the existence and uniqueness of periodic solutions for the first-order functional differential equation 𝑦(𝑡)=−𝑎(𝑡)𝑦(𝑡)+𝑓1(𝑡,𝑦(𝑡−𝜏(𝑡)))+𝑓2(𝑡,𝑦(𝑡−𝜏(𝑡))) with periodic coefficients and delays. We choose the mixed monotone operator theory to approach our problem because such metho...
