Transportation inequalities for stochastic differential equations of pure jumps
Annales de l'I.H.P. Probabilités et statistiques, Tome 46 (2010) no. 2, pp. 465-479.

Pour une équation différentielle stochastique de pur saut, bien que l'inégalité de Poincaré ne soit pas valide en général, nous pouvons quand même établir, sous la condition de dissipativité, des inégalités de transport W1H pour sa mesure invariante et pour sa loi (au niveau de processus) sur l'espace des trajectoires càdlàg, muni de la métrique L1 ou d'une métrique uniforme. Quelques applications aux inégalités de concentration sont présentées.

For stochastic differential equations of pure jumps, though the Poincaré inequality does not hold in general, we show that W1H transportation inequalities hold for its invariant probability measure and for its process-level law on right continuous paths space in the L1-metric or in uniform metrics, under the dissipative condition. Several applications to concentration inequalities are given.
