On the solutions of fractional random ordinary differential equations with the Residual power series method

open access: yesAlexandria Engineering Journal, 2023
In this study, random ordinary differential equations obtained by randomly choosing the coefficients or initial conditions of the ordinary differential equations will be analyzed by the Residual Power Series Method. The initial conditions or coefficients

Polynomial Time corresponds to Solutions of Polynomial Ordinary Differential Equations of Polynomial Length [PDF]

open access: yes, 2016
We provide an implicit characterization of polynomial time computation in terms of ordinary differential equations: we characterize the class $\operatorname{PTIME}$ of languages computable in polynomial time in terms of differential equations with ...

Lipschitz stability for generalized ordinary differential equations and impulsive retarded differential equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2019
We consider a class of retarded functional differential equations with preassigned moments of impulsive effect and we study the Lipschitz stability of solutions of these equations using the theory of generalized ordinary differential equations and ...

Pursuit Curves and Ordinary Differential Equations

open access: yesCommunications, 2012
This paper deals with the differential equations which describe curves of pursuit, in which the pursuer's velocity vector always points directly towards the pursued. We use the Laplace Transform method to solve the classic problem of four mice pursuit.

Fault Diagnosis via Neural Ordinary Differential Equations

open access: yesApplied Sciences, 2021
Implementation of model-based fault diagnosis systems can be a difficult task due to the complex dynamics of most systems, an appealing alternative to avoiding modeling is to use machine learning-based techniques for which the implementation is more ...

The remarkable effectiveness of time-dependent damping terms for second order evolution equations [PDF]

open access: yes, 2015
We consider a second order linear evolution equation with a dissipative term multiplied by a time-dependent coefficient. Our aim is to design the coefficient in such a way that all solutions decay in time as fast as possible.

Model of the telegraph line and its numerical solution [PDF]

open access: yes, 2018
This paper deals with a model of the telegraph line that consists of system of ordinary differential equations, rather than partial differential telegraph equation. Numerical solution is then based on an original mathematical method. This method uses the

Painleve property and the first integrals of nonlinear differential equations

open access: yes, 2004
Link between the Painleve property and the first integrals of nonlinear ordinary differential equations in polynomial form is discussed. The form of the first integrals of the nonlinear differential equations is shown to determine by the values of the ...
