Sub-Riemannian Navier-Stokes system on the Heisenberg group: Weak solutions, well-posedness and smoothing effects
Adrien Tendani-Soler
This article is devoted to the derivation of the incompressible sub-Riemannian Euler and the sub-Riemannian Navier-Stokes systems, and the analysis of the last one in the case of t…
Comparison of Two Formulations for Computing Body Surface Potential Maps
Emma Lagracie, Lisl Weynans, Yves Coudière
In order to establish a link between the activation map and the body surface signals, we want to compute body potentials from activation maps and a frontlike approximation of the a…
A new look at the controllability cost of linear evolution systems with a long gaze at localized data
Roberta Bianchini, Vincent Laheurte, Franck Sueur
We revisit the classical issue of the controllability/observability cost of linear first order evolution systems, starting with ODEs, before turning to some linear first order evol…
Differential transmutations
Franck Sueur
Inspired by Gromov's partial differential relations, we introduce a notion of differential transmutation, which allows to transfer some local properties of solutions of a PDE to so…
