Asymptotic behavior of weighted quadratic variation of bi-fractional Brownian motion
Annales mathématiques Blaise Pascal, Volume 17 (2010) no. 1, pp. 165-181.

We prove, by means of Malliavin calculus, the convergence in L 2 of some properly renormalized weighted quadratic variations of bi-fractional Brownian motion (biFBM) with parameters H and K, when H<1/4 and K(0,1].

Nous utilisons le calcul de Malliavin pour montrer la convergence dans L 2 de la variation quadratique à poids du mouvement brownien bifractionnaire (biFBM) d’indices H et K lorsque H<1/4 et K(0,1].
