On the $D$ -stability problem for real matrices

Russell Johnson; Alberto Tesi — 1999

Bollettino dell'Unione Matematica Italiana

Vengono discusse delle condizioni sufficienti affinchè una matrice reale $A$ delle dimensioni $n \times n$ sia diagonalmente (o $D$ -) stabile. Esse includono delle ipotesi geometriche (condizioni degli ortanti), e un criterio che generalizza un criterio di Carlson. Inoltre si discute la $D$ -stabilità robusta per le matrici reali delle dimensioni $4 \times 4$

On the existence of periodic solutions of an hyperbolic equation in a thin domain

Russell Johnson; Mikhail Kamenskii; Paolo Nistri — 1997

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

For a nonlinear hyperbolic equation defined in a thin domain we prove the existence of a periodic solution with respect to time both in the non-autonomous and autonomous cases. The methods employed are a combination of those developed by J. K. Hale and G. Raugel and the theory of the topological degree.

The $D$ -stability problem for $4 \times 4$ real matrices

Serkan T. Impram; Russell Johnson; Raffaella Pavani — 2005

Archivum Mathematicum

We give detailed discussion of a procedure for determining the robust $D$ -stability of a $4 \times 4$ real matrix. The procedure begins from the Hurwitz stability criterion. The procedure is applied to two numerical examples.
