Characterizing matrices with -simple image eigenspace in max-min semiring
A matrix is said to have -simple image eigenspace if any eigenvector
belonging to the interval is the unique solution of the system in
. The main result of this paper is a combinatorial characterization of such
matrices in the linear algebra over max-min (fuzzy) semiring.
The characterized property is related to and motivated by the general
development of tropical linear algebra and interval analysis, as well as the
notions of simple image set and weak robustness (or weak stability) that have
been studied in max-min and max-plus algebras.Comment: 23 page
X-simple image eigencones of tropical matrices
We investigate max-algebraic (tropical) one-sided systems
where is an eigenvector and lies in an interval . A matrix is
said to have -simple image eigencone associated with an eigenvalue
, if any eigenvector associated with and belonging to
the interval is the unique solution of the system in
. We characterize matrices with -simple image eigencone geometrically and
combinatorially, and for some special cases, derive criteria that can be
efficiently checked in practice.Comment: 25 page
