Nous considérons des processus symétriques purement discontinus. Nous obtenons des estimations locales pour les probabilités de sortie d'une boule, la continuité hölderienne des fonctions harmoniques et des noyaux de la chaleur, et la convergence d'un suite de tels processus.
We consider symmetric processes of pure jump type. We prove local estimates on the probability of exiting balls, the Hölder continuity of harmonic functions and of heat kernels, and convergence of a sequence of such processes.
Mots clés : symmetric jump processes, Dirichlet forms, heat kernels, Harnack inequalities, weak convergence, non-local operators
