Abstract
Many evolutionary systems can be described by an abstract Cauchy problem governed by an operator matrix. Assuming this problem to be "one-sided coupled" and "well-posed" we study in this paper the positivity and the stability of the associated matrix semigroup. The abstract results are illustrated by several examples.File in questo prodotto:
