Notre but est d’étudier des propriétés de processus à accroissements stationnaires et indépendants sous une -espérance. Comme application, nous démontrons la caractérisation de la martingale de -mouvement Brownien et fournissons un théorème de décomposition trajectorielle pour le -mouvement Brownien généralisé.
Our purpose is to investigate properties for processes with stationary and independent increments under -expectation. As applications, we prove the martingale characterization of -Brownian motion and present a pathwise decomposition theorem for generalized -Brownian motion.
Mots clés : stationary increments, independent increments, martingale characterization, decomposition theorem, $G$-Brownian motion, $G$-expectation
