Abstract

Let {W(t); t≥0} be a standard Brownian motion. For a positive integer m, define a Gaussian process

$$X_m \left( t \right) = \frac{1}{{m!}}\int_0^t { \left( {t - s} \right)^m dW\left( s \right)} $$

. In this paper the liminf behavior of the increments of this process is discussed by establishing some probability inequalities. Some previous results are extended and improved.
