Partially delayed stabilizing feedbacks for Maxwell’s system. (English) Zbl 1158.93027

Summary: We consider, in a bounded and smooth domain, Maxwell’s equations with a delay term in the boundary or in the internal feedbacks. Under suitable assumptions we obtain exponential stability results. Some instability examples are also given.
