Singularly perturbed ordinary differential equations with dynamic limits

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 1996
Coupled slow and fast motions generated by ordinary differential equations are examined. The qualitative limit behaviour of the trajectories as the small parameter tends to zero is sought after. Invariant measures of the parametrised fast flow are employed to describe the limit behaviour, rather than algebraic equations which are used in the standard ...

Singularly Perturbed Ordinary Differential Equations with Nonautonomous Fast Dynamics

Journal of Dynamics and Differential Equations, 1999
The author considers the Cauchy problem \[ \begin{alignedat}{2} \frac{dx}{dt}&=f(x,y),\qquad& x(0)&=x_0, \\ \varepsilon\frac{dy}{dt}&=g(x,y,\frac{t}{\varepsilon}),\qquad& y(0)&=y_0, \end{alignedat} \tag{1} \] with \(x\in {\mathbb{R}}^n\), \(y\in {\mathbb{R}}^m\) and \(t\in[0,1]\). In the Levinson-Tichonov theory, a basic assumption is that solutions to

On a Perturbation in a Two-Parameter Ordinary Differential Equation of the Second Order

Canadian Mathematical Bulletin, 1971
Let us consider the linear system in the two parameters λ and μ; i. e.,1.11.2and where for the moment we shall assume both b(x) and q(x) are real-valued, continuous functions in [0, 1].

A Tau Method with Perturbed Boundary Conditions for Certain Ordinary Differential Equations

Numerical Algorithms, 2005
The author introduces a new form of the tau method in which not only the differential equations are perturbed in order to obtain a polynomial solution but also the initial conditions are simultaneoulsy perturbed. The advantages of the new method and its accuracy in terms of perturbations and errors are studied.
