Nordsieck Methods with Inherent Quadratic Stability

Pages 82-96 | Received 24 Aug 2010, Accepted 01 Mar 2011, Published online: 08 Apr 2011
 

Abstract

We derive suffcient conditions which guarantee that the stability polynomial of Nordsieck method for ordinary differential equations has only two nonzero roots. Examples of such methods up to order four are presented which are A-and L-stable. These examples were obtained by computer search using the Schurcriterion applied to the quadratic factor of the resulting stability polynomials.
