Exploring complicated behaviors of a delay differential equation
Mathematical Modelling and Control, 2023 Complicated behaviors of a delay differential equation are explored through the Euler discretization method. It rigorously shows that the corresponding discrete equation can be chaotic under some conditions, which reflects that there exist complicated ...

On the Oscillation of the Generalized Food-Limited Equations with Delay
Aceh International Journal of Science and Technology, 2012 The objective of the paper is to find conditions for the oscillation of the food-limited equation. We established conditions for the oscillation of all solutions of the generalized foodlimited equation by transforming the equation to a non-linear delay ...

Resonance Phenomena in a Scalar Delay Differential Equation with Two State-Dependent Delays [PDF]
SIAM Journal on Applied Dynamical Systems, 2016 We study a scalar delay differential equation (DDE) with two delayed feedback terms that depend linearly on the state. The associated constant-delay DDE, obtained by freezing the state dependence, is linear and without recurrent dynamics.
