A universal gap for non-spin quantum control systems
Jean-Paul Gauthier, Francesco Rossi
We prove the existence of a universal gap for minimum time controllability of finite dimensional quantum systems, except for some basic representations of spin groups. This is equi…
Generic Singularities of the 3D-Contact sub-Riemannian Conjugate Locus
Benoît Bonnet, Jean-Paul Gauthier, Francesco Rossi
In this paper, we extend and complete the classification of the generic singularities of the 3D-contact sub-Riemmanian conjugate locus in a neighbourhood of the origin.
Cortical-inspired image reconstruction via sub-Riemannian geometry and hypoelliptic diffusion
Ugo Boscain, Roman Chertovskih, Jean-Paul Gauthier +2
In this paper we review several algorithms for image inpainting based on the hypoelliptic diffusion naturally associated with a mathematical model of the primary visual cortex. In…
