Carleman estimate for the Navier–Stokes equations and applications [PDF]

open access: yesInverse Problems, 2022
Abstract For linearized Navier–Stokes equations, we first derive a Carleman estimate with a regular weight function. Then we apply it to establish conditional stability for the lateral Cauchy problem and finally we prove conditional stability estimates for the inverse source problem of determining a spatially varying divergence-free ...

Discrete Carleman estimates and three balls inequalities [PDF]

open access: yesCalculus of Variations and Partial Differential Equations, 2021
AbstractWe prove logarithmic convexity estimates and three balls inequalities for discrete magnetic Schrödinger operators. These quantitatively connect the discrete setting in which the unique continuation property fails and the continuum setting in which the unique continuation property is known to hold under suitable regularity assumptions.

Global Carleman estimate for the plate equation and applications to inverse problems

open access: yesElectronic Journal of Differential Equations, 2016
In this article, we establish a Carleman estimate for the plate equation in order to solve an inverse problem retrieving the zeroth-order term for a plate equation from boundary measurements.

Carleman estimates [PDF]

open access: yes
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 ...

Carleman Estimates for Some Thermoelasticity Systems

open access: yes, 2017
In this chapter, we establish Carleman estimates for a thermoelastic plate system and a thermoelastic system with residual stress as applications of the Carleman estimate in Chap. 4.

Controllability to trajectories of a Ladyzhenskaya model for a viscous incompressible fluid

open access: yesComptes Rendus. Mathématique, 2021
We consider the controllability of a viscous incompressible fluid modeled by the Navier–Stokes system with a nonlinear viscosity. To prove the controllability to trajectories, we linearize around a trajectory and the corresponding linear system includes ...

A Carleman estimate and an energy method for a first-order symmetric hyperbolic system [PDF]

open access: yes, 2022
For a symmetric hyperbolic system of the first order, we prove a Carleman estimate under some positivity condition concerning the coefficient matrices.
