✦ Synopsis
We study the possibility to control the moments of Wiener integrals of fractional Brownian motion with respect to the L p -norm of the integrand. It turns out that when the self-similarity index H ¿ 1 2 , we can have only an upper inequality, and when H ¡ 1 2 we can have only a lower inequality.

Let Xt be a standard d-dimensional Brownian motion with drift c started at a ÿxed X0, and let T be the hitting time for a sphere or concentric spherical shell. By using an appropriate martingale, a Laplace-Gegenbauer transform of the joint distribution of T and XT is determined.
