On the internal stability and asymptotic behavior of 2-D positive systems. (English) Zbl 0891.93046
The internal stability of homogeneous 2-D linear systems described by a nonnegative pair \((A, B)\) is characterized in terms of the spectrum of the matrix sum \(A+B\). Special classes of separable matrix pairs and those endowed with property \(L\) or with one-dimensional characteristic polynomial are analyzed. The problem of asymptotic free evolution of 2-D positive linear systems is also considered.
