Explicit Nordsieck second derivative general linear methods for ODEs
The paper deals with the construction of explicit Nordsieck second derivative general linear methods with \(s\) stages of order \(p\) with \(p=s\) and high stage order \(q=p\) with inherent Runge–Kutta or quadratic stability properties. Satisfying the order and stage order conditions together with inherent stability conditions leads to methods with ...

Consistency of Nordsieck Methods
Necessary and sufficient conditions for consistency of Nordsieck methods are obtained. The notion of essential-consistency is introduced and explained geometrically. Finally it is shown that if a $(k + 1)$-value Nordsieck method is pth order essentially-consistent, then $p \leqq k + 2$.

Explicit Nordsieck methods with quadratic stability
The authors present the construction of explicit Nordsieck methods with \(s\) stages of order \(p = s-1\) and stage order \(q = p\) with inherent quadratic stability and quadratic stability with large regions of absolute stability for ordinary differential equations \(y'=f(y),\;t\in [t_0,T]\), \(y(t_0)=y_0\), where \(f:\mathbb R^m\to\mathbb R^m\) is ...

On the Stability of Variable-Stepsize Nordsieck BDF Methods
Die Verf. studieren die asymptotische Stabilität der rückwärts genommenen Differentiationsformeln in Nordsieck-Form auf nichtäquidistanten Gittern. Bei einem Wechsel der Schrittweite wird die Nordsiecksche Interpolationstechnik verwandt. Damit sind bei der Stabilitätsanalyse die Normen der Produkte der sich mit dem Schrittweitenwechsel ebenfalls ...
