Construction of Dirichlet structures

We show how the construction of Dirichlet structures allow to equip the main probabilistic objects with Dirichlet forms. We emphasize the case of local white Dirichlet structures on the Poisson space and on the Wiener space. This yields tools for studying the existence of densities of functionals of processes.
