A semigroup approach to stochastic systems with input delay at the boundary
Said Hadd, Fatima Zahra Lahbiri
This work focuses on the well-posedness of abstract stochastic linear systems with boundary input delay and unbounded observation operators. We use product spaces and a semigroup a…
Controllability of vertex delay type problems by the regular linear systems approach
Y. El Gantouh, S. Hadd, A. Rhandi
In this paper, we study the well-posedness and approximate controllability of a class of network systems having delays and controls at the boundary conditions. The particularity of…
Well-posedness and approximate controllability of neutral network systems
Yassine El Gantouh, Said Hadd
In this paper, we study the concept of approximate controllability of retarded network systems of neutral type. On one hand, we reformulate such systems as free-delay boundary cont…
A functional analytic approach to infinite dimensional stochastic linear systems
Fatima-Zahra Lahbiri, Said Hadd
In this paper, we study infinite dimensional stochastic systems having both unbounded control and observation operators. First of all, using a semigroup approach, we give another t…
