On the strong stability of symplectic matrices
Mouhamadou Dosso, Miloud Sadkane · Numerical Linear Algebra with Applications · 2011
SUMMARY The strong stability of a symplectic matrix is investigated from algorithmic and numerical viewpoints using a theory developed by S.K. Godunov. This theory is based on a different formulation of the Krein‐Gelfand‐Lidskii characterization of strong stability, better suited for numerical calculations. Copyright © 2011 John Wiley & Sons, Ltd.
