Let {W(t), t greater than or equal to 0} be a standard Brownian motion. For
a positive integer m, define a Gaussian process
X-m(t) = 1/m! integral (t)(0) (t - s)(m) dW(s).
Watanabe and Lachal gave some asymptotic properties of the process X-m(.),
m greater than or equal to 1. In this paper, we study the bounds of its mod
uli of continuity and large increments by establishing large deviation resu
lts.
