Automated Linearization of a System of Nonlinear Ordinary Differential Equations

open access: yesInternational Journal of Electronics and Telecommunications, 2023
This paper investigates the possibility of automatically linearizing nonlinear models. Constructing a linearised model for a nonlinear system is quite labor-intensive and practically unrealistic when the dimension is greater than 3. Therefore, it is important to automate the process of linearisation of the original nonlinear model.

First Integrals and Exact Solutions of a System of Ordinary Differential Equations with Power Nonlinearity

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
The system of ordinary differential equations with degree nonlinearities is considered. Systems of such kind arise as comparison systems at stability analysis by means non-linear approximation and at application of reduction method to switched systems ...

Boundedness and stability in nonlinear systems of differential equations using a modified variation of parameters formula

open access: yesCubo, 2023
In this research we introduce a new variation of parameters for systems of linear and nonlinear ordinary differential equations. We use known mathematical methods and techniques including Gronwall’s inequality and fixed point theory to obtain boundedness

Oscillation and asymptotic behavior of systems of ordinary linear differential equations [PDF]

open access: yesTransactions of the American Mathematical Society, 1979
Conditions are established for oscillatory and asymptotic behavior for first-order matrix systems of ordinary differential equations, including Hamiltonian systems in the selfadjoint case. Asymptotic results of Hille, Shreve, and Hartman are generalized. Disconjugacy criteria of Ahlbrandt, Tomastik, and Reid are extended.
