The existence of periodic solutions for three-order neutral differential equations
Manna Huang,Chengjun Guo,Junming Liu
Keywords:Periodic solutions, multiple deviating arguments, neutral differential equation
Abstract:
      In this note, we establish two diverse results of periodic solutions for a class of three-order neutral differential equations with multiple deviating arguments. One is on the basis of Kranoselskii fixed point theorem, and the other is on the basis of Mawhin"s continuation theorem.
