On existence of periodic solutions of the Rayleigh equation of retarded type
International Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 1, Page 65-68, 2000., 2000 In this paper, we give two sufficient conditions on the existence of periodic solutions of the non‐autonomous Rayleigh equation of retarded type by using the coincidence degree theory.

Branches of Forced Oscillations Induced by a Delayed Periodic Force
Advanced Nonlinear Studies, 2019 We study global continuation properties of the set of T-periodic solutions of parameterized second order delay differential equations with constant time lag on smooth manifolds. We apply our results to get multiplicity of T-periodic solutions.

Delay differential equations: a partially ordered sets approach in vectorial metric spaces
Fixed Point Theory and Applications, 2014 In this paper we develop a fixed point theorem in the partially ordered vector metric space C([−τ,0],Rn) by using vectorial norm. Then we use it to prove the existence of periodic solutions to nonlinear delay differential equations.

Journal of Inequalities and Applications, 2014 This paper is concerned with the global exponential convergence of Cohen-Grossberg neural networks with continuously distributed leakage delays. By using the Lyapunov functional method and differential inequality techniques, we propose a new approach to ...

On the stability of periodic orbits in delay equations with large delay [PDF]
, 2011 We prove a necessary and sufficient criterion for the exponential stability of periodic solutions of delay differential equations with large delay. We show that for sufficiently large delay the Floquet spectrum near criticality is characterized by a set ...

, 2018 We obtain a new quantitative deformation lemma, and then gain a new mountain pass theorem. More precisely, the new mountain pass theorem is independent of the functional value on the boundary of the mountain, which improves the well known results (\cite ...

Global exponential stability of nonautonomous neural network models with continuous distributed delays [PDF]
, 2013 For a family of non-autonomous differential equations with distributed delays, we give sufficient conditions for the global exponential stability of an equilibrium point. This family includes most of the delayed models of neural networks of Hopfield type,
