Dynamics of a May-Leonard asymmetric system of ordinary differential equations

open access: yesElectronic Journal of Differential Equations
We study the May-Leonard asymmetric model in $R^3$ which was introduced in [3,8]. It is the celebrated classical May-Leonard model incorporating asymmetric competitive effects instead of requiring equal intrinsic growth rates for each competing ...

Integrals of ν-graded systems of ordinary differential equations

open access: yesJournal of Pure and Applied Algebra, 1987
The problem of finding integrals of a system of n first-order differential equations is discussed: \[ Dy_ i=f_ i(y)\quad (i=1,...,n)\quad,\quad y=(y_ 1,...,y_ n) \] where the \(f_ i's\) are infinite series of rational functions in y and K, the field of coefficients, is a differential field. The author obtains an algorithm which yields all integrales of

Study of fully coupled three-dimensional envelope instability using automatic differentiation

open access: yesPhysical Review Accelerators and Beams
Automatic differentiation is a powerful tool for computing derivatives of simulation results with respect to given parameters. In this Letter, we have applied this tool to investigate the instability of a dynamical system governed by 21 ordinary ...

On the variational principle for a system of ordinary differential equations

open access: yesСовременная математика: Фундаментальные направления
Necessary and sufficient conditions for the direct representability of one system of ordinary differential equations in the form of Lagrange-Ostrogradsky equations are obtained and the corresponding variational principle (the Hamilton-Ostrogradsky action)

Periodic Solution for Nonlinear System of Differential Equations Depending on The Gamma Distribution

open access: yesScience Journal of University of Zakho, 2014
In this paper we study the periodic solution of nonlinear system of differential equations depending on the gamma distribution by using the numerical analytic method to investigate periodic solutions of ordinary differential equation which given by ...
