At the close of the 1980s, the independent contributions of Yann Brenier, Mike Cullen and John Mather launched a revolution in the venerable field of optimal transport founded by G. Monge in the 18th century, which has made breathtaking forays into various other domains of mathematics ever since. The author presents a broad overview of this area, supplying complete and self-contained proofs of all the fundamental results of the theory of optimal transport at the appropriate level of generality. Thus, the book encompasses the broad spectrum ranging from basic theory to the most recent...

Leading researchers in the field of Optimal Transportation, with different views and perspectives, contribute to this Summer School volume: Monge-Ampere and Monge-Kantorovich theory, shape optimization and mass transportation are linked, among others, to applications in fluid mechanics granular material physics and statistical mechanics, emphasizing the attractiveness of the subject from both a theoretical and applied point of view.

The volume is designed to become a guide to researchers willing to enter into this challenging and useful theory.

Cet ouvrage applique les algorithmes a Regimes Glissants (RG) aux boucles industrielles de regulation et d'asservissement pilotees jusqu'a ce jour par les traditionnels PID et leurs variantes (RST, etc.). Le systeme reel a commander peut etre de nature variee, avoir des parties mal ou non modelisees, etre soumis a des perturbations. Les algorithmes numeriques robustes RG calculent une commande ayant une composante discontinue et donnent une evolution du point de fonctionnement du systeme boucle sur la surface de glissement (l'equation de la surface definit la dynamique du systeme boucle)....

With each methodology treated in its own chapter, this monograph is a thorough exploration of several theories that can be used to find explicit formulas for heat kernels for both elliptic and sub-elliptic operators. The authors show how to find heat kernels for classical operators by employing a number of different methods. Some of these methods come from stochastic processes, others from quantum physics, and yet others are purely mathematical. Depending on the symmetry, geometry and ellipticity, some methods are more suited for certain operators rather than others.
