Periodic Solutions of a Periodic FitzHugh–Nagumo System [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2015
Recently some interest has appeared for the periodic FitzHugh–Nagumo differential systems. Here, we provide sufficient conditions for the existence of periodic solutions in such differential systems.

ON PERIODIC SOLUTIONS OF 2-PERIODIC LYNESS' EQUATIONS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2013
We study the existence of periodic solutions of the nonautonomous periodic Lyness' recurrenceun+2 = (an + un+1)/un, where {an}n is a cycle with positive values a, b and with positive initial conditions. It is known that for a = b = 1 all the sequences generated by this recurrence are 5-periodic.

Discontinuous bifurcations of periodic solutions

open access: yesMathematical and Computer Modelling, 2002
The authors discuss some aspects of bifurcations of periodic solutions in systems with a discontinuous vector field. Using the example \[ m\ddot x+C(\dot x) + K(x) = f_0\sin(\omega t), \] the authors demonstrate, under certain assumptions on the functions \(K(x)\) and \(C(\dot x)\), how the Floquet multipliers of a discontinuous system can jump when ...

Dynamic Complexity in a Prey-Predator Model with State-Dependent Impulsive Control Strategy

open access: yesComplexity, 2020
In this paper, an ecological model described by a couple of state-dependent impulsive equations is studied analytically and numerically. The theoretical analysis suggests that there exists a semitrivial periodic solution under some conditions and it is ...

The Periodic Solution of Fractional Oscillation Equation with Periodic Input

open access: yesAdvances in Mathematical Physics, 2013
The periodic solution of fractional oscillation equation with periodic input is considered in this work. The fractional derivative operator is taken as  -∞Dtα, where the initial time is -∞; hence, initial conditions are not needed in the model of the ...

Anti-periodic solution for fuzzy differential equations

open access: yes上海师范大学学报. 自然科学版, 2021
In this paper, using differential inclusions’ approach, we obtain existence results of antiperiodic solutions for a class of fuzzy differential equations. An example shows the feasibility of the main results.

PERIODIC SOLUTIONS AND SLOW MANIFOLDS [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2007
After reviewing a number of results from geometric singular perturbation theory, we give an example of a theorem for periodic solutions in a slow manifold. This is illustrated by examples involving the van der Pol-equation and a modified logistic equation.
