Regularity theory and geometry of unbalanced optimal transport
Thomas Gallouët, Roberta Ghezzi, François-Xavier Vialard
Using the dual formulation only, we show that the regularity of unbalanced optimal transport also called entropy-transport inherits from the regularity of standard optimal transpor…
Optimal control of a bioreactor for biofuel production
Roberta Ghezzi, Benedetto Piccoli
Dynamic flux balance analysis of a bioreactor is based on the coupling between a dynamic problem, which models the evolution of biomass, feeding substrates and metabolites, and a l…
Regularization of chattering phenomena via bounded variation control
Marco Caponigro, Roberta Ghezzi, Benedetto Piccoli +1
In control theory, the term chattering is used to refer to strong oscillations of controls, such as an infinite number of switchings over a compact interval of times. In this paper…
The sphere and the cut locus at a tangency point in two-dimensional almost-Riemannian geometry
Bernard Bonnard, Grégoire Charlot, Roberta Ghezzi +1
We study the tangential case in 2-dimensional almost-Riemannian geometry. We analyse the connection with the Martinet case in sub-Riemannian geometry. We compute estimations of the…
Normal forms and invariants for 2-dimensional almost-Riemannian structures
Ugo Boscain, Grégoire Charlot, Roberta Ghezzi
Two-dimensional almost-Riemannian structures are generalized Riemannian structures on surfaces for which a local orthonormal frame is given by a Lie bracket generating pair of vect…
Lipschitz classification of almost-Riemannian distances on compact oriented surfaces
Ugo Boscain, Grégoire Charlot, Roberta Ghezzi +1
Two-dimensional almost-Riemannian structures are generalized Riemannian structures on surfaces for which a local orthonormal frame is given by a Lie bracket generating pair of vect…
