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…

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…
