Periodic dynamics of a general switching dynamical system

open access: yesEuropean Journal of Applied Mathematics
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.

Existence of solutions and stability for impulsive neutral stochastic functional differential equations [PDF]

open access: yes, 2019
In this paper we prove some results on the existence of solutions and the mean square asymptotic stability for a class of impulsive neutral stochastic differential systems with variable delays by using a contraction mapping principle.

On the existence of forced oscillations of retarded functional motion equations on a class of topologically nontrivial manifolds [PDF]

open access: yes, 2012
Using a topological approach, based on the fixed point index theory for locally compact maps on metric ANRs, we prove the existence of forced oscillations for retarded functional motion problems constrained on compact manifolds with nontrivial Euler ...

The unstable set of a periodic orbit for delayed positive feedback

open access: yes, 2014
In the paper [Large-amplitude periodic solutions for differential equations with delayed monotone positive feedback, JDDE 23 (2011), no. 4, 727--790], we have constructed large-amplitude periodic orbits for an equation with delayed monotone positive ...

A two state model for noise-induced resonance in bistable systems with delay [PDF]

open access: yes
The subject of the present paper is a simplified model for a symmetric bistable system with memory or delay, the reference model, which in the presence of noise exhibits a phenomenon similar to what is known as stochastic resonance.
