Phase Portraits of a Class of Continuous Piecewise Linear Differential Systems. [PDF]

open access: yesDiffer Equ Dyn Syst, 2023
Abstract The phase portraits of the planar linear differential systems are very well known. This is not the case for the phase portraits of the planar continuous piecewise linear differential systems. In this paper we classify the phase portraits of the class of planar continuous piecewise linear differential systems of the form

On the periodic solutions of the Michelson continuous and discontinuous piecewise linear differential system [PDF]

open access: yesComputational and Applied Mathematics, 2016
Applying new results from the averaging theory for continuous and discontinuous differential systems, we study the periodic solutions of two distinct versions of the Michel- son differential system: a Michelson continuous piecewise linear differential system and a Michelson discontinuous piecewise linear differential system.

Phase portraits of continuous piecewise linear Liénard differential systems with three zones [PDF]

open access: yesChaos, Solitons & Fractals, 2021
Phase portraits are an invaluable tool in studying differential systems. Most of known results about global phase portraits are related to the smooth differential systems. This paper deals with a class of planar continuous piecewise linear Liénard differential systems with three zones separated by two vertical lines without symmetry.

On limit cycles of piecewise differential systems formed by arbitrary linear systems and a class of quadratic systems [PDF]

open access: yesMathematica Bohemica, 2023
We study the continuous and discontinuous planar piecewise differential systems separated by a straight line and formed by an arbitrary linear system and a class of quadratic center.

The Markus–Yamabe conjecture for continuous and discontinuous piecewise linear differential systems [PDF]

open access: yesProceedings of the American Mathematical Society, 2021
In 1960 Markus and Yamabe made the following conjecture: If a C 1 C^1 differential system x ˙ = F ( x ) \dot {\mathbf {x}}=F(\mathbf {x}) in R

LIMIT CYCLES FOR A CLASS OF CONTINUOUS PIECEWISE LINEAR DIFFERENTIAL SYSTEMS WITH THREE ZONES [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2012
In this paper, we consider a class of planar continuous piecewise linear vector fields with three zones. Using the Poincaré map, we show that these systems admit always a unique limit cycle, which is hyperbolic.

Limit cycles of planar piecewise linear Hamiltonian differential systems with two or three zones

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper, we study the existence of limit cycles in continuous and discontinuous planar piecewise linear Hamiltonian differential system with two or three zones separated by straight lines and such that the linear systems that define the piecewise ...

Phase portraits of piecewise linear continuous differential systems with two zones separated by a straight line [PDF]

open access: yesJournal of Differential Equations, 2021
This paper provides the classification of the phase portraits in the Poincaré disc of all piecewise linear continuous differential systems with two zones separated by a straight line having a unique finite singular point which is a node or a focus. The sufficient and necessary conditions for existence and uniqueness of limit cycles are also given.
