Precisely speaking, we characterize the convergence in total variation to target distributions which are not Gaussian or Gamma distributed, in terms of the Malliavin calculus and of the coefficients of the associated diffusion process. We also prove that, among the distributions whose associated squared diffusion coefficient is a polynomial of second degree (with some restrictions on its coefficients), the only possible limits of sequences of multiple integrals are the Gaussian and the Gamma laws.", "revisions": [ { "version": "v1", "updated": "2013-10-14T18:51:47.000Z", "title": "Extension of the Fourth Moment Theorem to invariant measures of diffusions", "abstract": "We characterize the convergence in distribution of a sequence of random variables in a Wiener chaos of a fixed order to a probability distribution which is the invariant measure of a diffusion process.
