摘要: In many PDEs models some constraints need to be imposed when considering concrete applications. This is for instance the case of evolutionary systems (such as heat conduction, transportation networks, population dynamic, etc.) where realistic models must incorporate the consideration that the state should adhere to some positivity constraints to ensure their physical relevance. In this talk, we discuss the concept of well-posed and regular linear systems, in a Banach lattice setting, with a particular aim to explore new techniques and new questions for positive infinite-dimensional linear systems. We describe the structural properties of admissible control/observation operators. Then, we present criteria for well-posedness, positivity and stability of infinite-dimensional linear systems with unbounded input and output operators.
