Exact controllability for systems describing plate vibrations. A perturbation approach

Comptes Rendus. Mathématique
The aim of this paper is to prove new exact controllability properties of systems described by perturbations of the classical Kirchhoff plate equation. We first consider systems described by an abstract plate equation with a bounded control operator. The

Biregular Mappings on $\mathbb{H}\times \mathbb{H}$: Domains of Hyperholomorphy, Integral Representations, and Runge Approximation

Mathematics
We develop a PDE and boundary integral framework for quaternion-valued fields on product domains Ω⊂H×H governed by the mixed left/right Cauchy–Fueter system We identify the natural compatibility condition and prove local solvability with quantitative H1 ...

Carleman estimates

This work aims to study Carleman estimates, a weighted-type of inequalities first introduced by Carleman in 1939. Such estimates are very important for proving unique continuation properties of differential and pseudo-differential operators. We first derive a Carleman estimate for the Laplacian operator as an illustrative example following the work of ...
