We propose an overview of the modeling approaches for the mathematical description and
analysis of processes that combine continuous and discontinuous behavior, namely …

[HTML][HTML] On the orbital Hausdorff dependence of differential equations with non-instantaneous impulses

D Yang, JR Wang, D O'Regan - Comptes Rendus Mathematique, 2018 - Elsevier
In this article, we investigate the orbital Hausdorff continuous dependence of the solutions to
integer order and fractional nonlinear non-instantaneous differential equations. The concept …

Non-instantaneous impulsive fractional-order implicit differential equations with random effects

D Yang, JR Wang - Stochastic Analysis and Applications, 2017 - Taylor & Francis
In this article, we study existence and stability of a class of non-instantaneous impulsive
fractional-order implicit differential equations with random effects. First, we establish a …

Stability of nonlinear variable-time impulsive differential systems with delayed impulses

Z He, C Li, Z Cao, H Li - Nonlinear Analysis: Hybrid Systems, 2021 - Elsevier
This paper investigates the stability of nonlinear variable-time impulsive differential systems
with delayed impulses. By using the comparison principle, the Lyapunov method and …

[HTML][HTML] Pulse vaccination in a SIR model: Global dynamics, bifurcations and seasonality

JPSM de Carvalho, AA Rodrigues - Communications in Nonlinear Science …, 2024 - Elsevier
We analyze a periodically-forced dynamical system inspired by the SIR model with
impulsive vaccination. We fully characterize its dynamics according to the proportion p of …
