Numerical Methods for Stiff, Quadratic and Josephson Interferometer Differential Equations.

1980
Abstract : THE TWO-PARAMETER CLASS OF ALL A-contractive two-step second-order formulas was derived for arbitrary step ratios. Similarly, the one-parameter class of all A-constractive two-step second-order formulas was derived for arbitrary step ratios. A specific A-contractive formula was derived which minimizes a measure of the global truncation error.

Singular Perturbation for Stiff Equations Using Numerical Methods

1985
The present paper explores the following question: can the number-crunching power of the computer be used not only for generating numerical solutions, but also for deriving alternative formulations for the given problems? In other words, can the traditional role of human theoreticians also be performed by digital computers?

A block method for the numerical integration of stiff systems of ordinary differential equations

BIT, 1979
A new approach to the approximate numerical integration of stiff systems of first order ordinary differential equations is developed. In this approach several different formulae are applied in a well defined cyclic order to produce highly accurate integration schemes with infinite regions of absolute stability.

Numerical methods with equation-dependent coefficients for stiff differential problems

2022
The aim of this talk is to show techniques that allow to modify the coefficients of classic explicit numerical methods, improving their accuracy and stability properties, for the solution of ordinary differential equations systems of the following form: y′=f(t,y(t)) (3). The new methods coefficients depend on the Jacobian of the problem (3). In detail,

Numerical Methods for Stiff Nonlinear and Quadratic Differential Equations.

1977
Abstract : First, results are given concerning input-output stability and Liapunov variational stability of nonlinear multistep difference equations. They state that formulas which are A-stable, or possess other similar linear properties of unconditional fixed-h stability, are stable also when applied to certain representative classes/of (eg, monotone)

A class of A(α)-stable numerical methods for stiff problems in ordinary differential equations

Numerical Analysis and Applications, 2013
Summary: Some \(A(\alpha)\)-stable numerical methods for the number of steps \(k\leq 7\) for stiff initial value problems in ordinary differential equations are proposed. The discrete schemes proposed from their equivalent continuous schemes are obtained.

A projection method for the numerical solution of linear systems in separable stiff differential equations

International Journal of Computer Mathematics, 1989
This paper deals with the efficient implementation of implicit methods for solving stiff ODEs, in the case of Jacobians with separable sets of eigenvalues. For solving the linear systems required we propose a method which is particularly suitable when the large eigenvalues of the Jacobian matrix are few and well separated from the small ones.

On one class of numerical methods for solving stiff systems of differential equations

Vestnik St. Petersburg University: Mathematics, 2012
The paper is concerned with a modification of a Cowell-type method: at each step the solution is evaluated at several points and only some first of these values are retained. Stability of these methods is examined. In particular, among the methods of this group we single out one method that has the fourth order of accuracy and is stable for stiff ...
