Sign patterns that require a positive or nonnegative left inverse.
On determining minimal spectrally arbitrary patterns.
Generating potentially nilpotent full sign patterns.
Symmetric sign patterns with maximal inertias
The inertia of an by symmetric sign pattern is called maximal when it is not a proper subset of the inertia of another symmetric sign pattern of order . In this note we classify all the maximal inertias for symmetric sign patterns of order , and identify symmetric sign patterns with maximal inertias by using a rank-one perturbation.
Sign patterns that allow eventual positivity.
