Symmetric sign patterns with maximal inertias

In-Jae Kim; Charles Waters — 2010

Czechoslovak Mathematical Journal

The inertia of an $n$ by $n$ symmetric sign pattern is called maximal when it is not a proper subset of the inertia of another symmetric sign pattern of order $n$ . In this note we classify all the maximal inertias for symmetric sign patterns of order $n$ , and identify symmetric sign patterns with maximal inertias by using a rank-one perturbation.

Sign patterns that allow eventual positivity.
