The Stability of Variable-Stepsize Nordsieck Methods

open access: closedSIAM Journal on Numerical Analysis, 1983
Conditions are given for the stability of multistep methods that vary the stepsize using the interpolation technique of Nordsieck. If the stepsize selection function is variation-bounded, then these methods are stable. Alternatively there exist constants a, b, c depending on the method and satisfying $a \leqq b < 1 < c$ such that if the stepsize ratio $

Transverse-momentum distribution from the Bloch-Nordsieck method

open access: closedPhysical Review D, 1977
The transverse-momentum distribution is studied using the Bloch-Nordsieck method. An approximate analytic form for the above distribution is found, which maintains the normalization as well as reproduces the exact result for the average (squared) transverse momentum, $〈{{k}_{\ensuremath{\perp}}}^{2}〉$. For large ${k}_{\ensuremath{\perp}}$, our proposed

Polaron Self-Energy and Bloch-Nordsieck Method

open access: closedPhysical Review, 1954
By using the Bloch-Nordsieck method the self-energy of a polaron has been investigated in two limiting cases: (i) when the polaron velocity is low, i.e., mv 2 ħω, and (ii) when the velocity is high, i.e., mv 2 ħω. In case (i), this method gives results which are no better than those obtained by the use of the customary second-order perturbation theory,

On the Stability of Interpolatory Variable-Stepsize Adams Methods in Nordsieck Form

open access: closedSIAM Journal on Numerical Analysis, 1989
In the existing ODE codes stepsize controls are incorporated. In order to ensure the stability of the integration process restrictions on the stepsize variation must be imposed. The authors consider various strategies for the stepsize selection and corresponding conditions for the allowable ratio \(h_{j+1}/h_ j\) of consecutive stepsize for the Adams ...

A Class of Variable-Step Explicit Nordsieck Multivalue Methods

open access: closedSIAM Journal on Numerical Analysis, 1994
Exploratory results are presented for a class of variable-step, three- step, three-stage, explicit Nordsieck multivalue methods of order six. The aim is to demonstrate that the new methods are potentially more efficient than existing methods of the same order. Numerical comparisons are given.
