Periodic solutions of periodic generalized food limited model
By using the continuation theorem of coincidence degree theory, the existence of positive periodic solutions for a periodic generalized food limited model with state dependent delays and distributed delays is studied, respectively.

On existence of periodic solutions of the Rayleigh equation of retarded type
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
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.

Slowly oscillating solutions of a Van der Pol oscillator with state-dependent delay
In this paper, we consider a Van der Pol oscillator with state-dependent delay. First, we seek a suitable set E on which we construct a Poincaré operator F. Then, we prove that the operator F is continuous and compact on E \ {0}.

The dynamical analysis of a nonlocal predator–prey model with cannibalism
Cannibalism is often an extreme interaction in the animal species to quell competition for limited resources. To model this critical factor, we improve the predator–prey model with nonlocal competition effect by incorporating the cannibalism term, and ...

Periodic dynamics of a general switching dynamical system
Seasonal changes and cyclical human activities (such as periodic fishing bans, Wolbachia-based mosquito population control, and school term breaks) have significant impacts on population dynamics.
