Energy Decay Induced by Localized Coercivity in the 3D Navier--Stokes Equations
Amadou Cissé
Energy-based analysis of the three-dimensional incompressible Navier--Stokes equations with spatially localized dissipation is developed at the level of kinetic energy and Leray--H…

Structural Compatibility and Uniform Stability of Temporally Degenerate Parabolic Systems
Amadou Cissé
Modern feedback design for distributed parameter systems presupposes that the closed-loop dynamics define a well-posed evolution problem. This presupposition becomes nontrivial for…

Operator-Theoretic Stability and Observer Synthesis for Parameter-Dependent Vlasov--Maxwell Dynamics
Amadou Cissé, Mohamed Boutayeb
An operator--theoretic formulation is developed for the synthesis of parameter-dependent controllers and observers for the Vlasov--Maxwell system. The linearized dynamics are model…
