Dichotomies and stability in singularly perturbed systems of O.D.E.

Nonlinear Analysis: Theory, Methods & Applications, 1987
The authors consider the singularly perturbed initial value problem \((1.1a)\quad \dot x=F(t,x,y,\epsilon),\) \(x(0)=x^ 0\), \((1.1b)\quad \epsilon \dot y=G(t,x,y,\epsilon),\) \(y(0)=y^ 0\), where \(x,F\in {\mathbb{R}}^ n\) and \(y,G\in {\mathbb{R}}^ m\).

Singularly perturbed nonlinear ODEs and interior point optimization algorithms

Proceedings of 1995 American Control Conference - ACC'95, 2005
This paper explores the continuous realizations of iterative processes emanating from interior point optimization algorithms, and their connection with nonlinear singularly-perturbed ordinary differential equations. This mathematical connection provides a theoretical framework for the analysis of the dynamical properties long known and exploited in ...

On singularly perturbed systems of ODE with a multiple root of the degenerate equation

Izvestiya: Mathematics, 2020
Abstract We consider a boundary-value problem for a system of two second-order ODE with distinct powers of a small parameter at the second derivative in the first and second equations. When one of the two equations of the degenerate system has a double root, the asymptotic behaviour of the boundary-layer solution of the boundary-value

A Parameter-Uniform Tailored Finite Point Method for Singularly Perturbed Linear ODE Systems

Journal of Computational Mathematics, 2013
In scientific applications from plasma to chemical kinetics, a wide range of temporal scales can present in a system of differential equations. A major difficulty is encountered due to the stiffness of the system and it is required to develop fast numerical schemes that are able to access previously unattainable parameter regimes.

Ordinary differential equations (ODEs) on inertial manifolds for reaction-diffusion systems in a singularly perturbed domain with several thin channels

Journal of Dynamics and Differential Equations, 1992
The authors are dealing with some complicated domain and a reaction diffusion system on it. In nonlinear PDE problems, it is not easy to obtain a sharp result concerning the solutions and their structure in a general situation because many essentially different situations can occur in different cases.

Entirely Exponential-Type Scheme (E2S) for Optimization Problems with Singularly Perturbed ODE Constraints: The Model Problem

Numerical Mathematics: Theory, Methods and Applications
We found that no convergence to the correct solution can happen when a popular method is applied to discretize the derivative appearing in the objective function for optimization problems with singularly perturbed ODE constraints. The non-convergence mentioned above can occur even if the error bound of the numerical solution of the state equation has ...
