Regional Boundary Exact Controllability of the Wave Equation by Strategic Actuators on a Polygonal Domain with Cracks

Cheikh Seck, Ousmane Sène & Teuw Niane · Journal of Advances in Mathematics and Computer Science · 2020

In this work we prove the exact controllability of the wave equation by acting on a strategic zone of the border of a non-convex polygonal domain with crack. Indeed, by combining two methods: that of Grisvard on the exact controllability on domains with corners and that of EL. Ja...

Internal Exact Controllability of the Heat Equation in Finite Dimension by Strategic Actuators Zone

Mame Libasse Laye Ane, Cheikh Seck, Abdoulaye Sene & Mary Teuw Niane · Journal of Advances in Mathematics and Computer Science · 2021

In this paper, we show, by a new approach called SCD (Surjectivity by compactness and density), the internal exact controllability of the 1D heat equation by the use of strategic zone actuators. For the achievement of this objective, an operator (linear, continuous and surjective...
