Multiple Positive Periodic Solutions for Delay Differential System
Discrete Dynamics in Nature and Society, 2009 We obtain some existence results for multiple positive periodic solutions of some delay differential systems. Examples are presented as applications. For a general positive integer m≥2, main results of this paper do not appear in former literatures as we

Periodic Solutions of a System of Delay Differential Equations for a Small Delay
Sultan Qaboos University Journal for Science, 2002 We prove the existence of an asymptotically stable periodic solution of a system of delay differential equations with a small time delay t > 0. To achieve this, we transform the system of equations into a system of perturbed ordinary differential ...
