“…For an example of an application of this approach to population models in biology we refer to [4]. The stability and control problems of linear flows in networks using semigroup approach were investigated in [16,17,25,7]. Our aim here is to further generalize and refine these latter results.…”
We characterize the space of all exactly reachable states of an abstract boundary control system using a semigroup approach. Moreover, we study the case when the controls of the system are constrained to be positive. The abstract results are then applied to study flows in networks with static as well as dynamic boundary conditions.

“…Under the above assumptions and for u ∈ L 1 loc (R + , U ), the authors in [1,4,5] have been shown that if x is a classical solution of (BCP ), i.e. x(•) ∈ C 1 (R + , X) with x(t) ∈ D(A m ) for all t ≥ 0 satisfying the boundary systems (BCP ), then it is given by the variation of constat formula…”

“…Consequently the controllability in the usual sense is impossible. The notion of approximate positive controllability of boundary positive control systems has been studied in [1,2]. By applying the above theory we study and characterize the approximate positive controllability of boundary positive control of Lotka-McKendrick system.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
