Abstract: | We consider a -parameter Hermite process with Hurst index and we study its limit behavior in distribution when the Hurst parameters (or a part of them) converge to and/or 1. The limit obtained is Gaussian (when at least one parameter tends to ) and non-Gaussian (when at least one-parameter tends to 1 and none converges to ). |
