Iterative Solution of Piecewise Linear Systems [PDF]

open access: yesSIAM Journal on Scientific Computing, 2008
The correct formulation of numerical models for free-surface hydrodynamics often requires the solution of special linear systems whose coefficient matrix is a piecewise constant function of the solution itself. In so doing one may prevent the development of unrealistic negative water depths.

A generalized approach for implicit time integration of piecewise linear/nonlinear systems

open access: yesInternational Journal of Mechanical System Dynamics, 2021
A generalized solution scheme using implicit time integrators for piecewise linear and nonlinear systems is developed. The piecewise linear characteristic has been well‐discussed in previous studies, in which the original problem has been transformed ...

Identification of Piecewise Linear Models of Complex Dynamical Systems [PDF]

open access: yes, 2011
The paper addresses the realization and identification problem or a subclass of piecewise-affine hybrid systems. The paper provides necessary and sufficient conditions for existence of a realization, a characterization of minimality, and an ...

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 ...

Simultaneous occurrence of sliding and crossing limit cycles in piecewise linear planar vector fields [PDF]

open access: yes, 2019
In the present study we consider planar piecewise linear vector fields with two zones separated by the straight line $x=0$. Our goal is to study the existence of simultaneous crossing and sliding limit cycles for such a class of vector fields.

Piecewise-linear and birational toggling [PDF]

open access: yes, 2014
We define piecewise-linear and birational analogues of the toggle-involutions on order ideals of posets studied by Striker and Williams and use them to define corresponding analogues of rowmotion and promotion that share many of the properties of ...

Crossing limit cycles for piecewise linear differential centers separated by a reducible cubic curve

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
As for the general planar differential systems one of the main problems for the piecewise linear differential systems is to determine the existence and the maximum number of crossing limits cycles that these systems can exhibit.

Bifurcation Phenomena in Two-Dimensional Piecewise Smooth Discontinuous Maps [PDF]

open access: yes, 2008
In recent years the theory of border collision bifurcations has been developed for piecewise smooth maps that are continuous across the border, and has been successfully applied to explain nonsmooth bifurcation phenomena in physical systems.

Piecewise continuous approach to nonlinear differential equations approximation problem of computational structural mechanics

open access: yesMATEC Web of Conferences, 2018
This paper presents a nonlinear differential equations system piecewise continuous approximation. The piecewise continuous approximation improves piecewise linear approximation through reducing the errors at the boundaries of different linear ...
