摘要 本文设β(s)表示R^2空间中的布朗运动,|W_r(t)|是由β(s)产生的到时刻t的Wiener sausage.利用Wiener sausage的分解技巧以及一些指数矩估计,得到一个关于|W_r(t)|-E|W_r(t)|的中偏差. Let β(s) be the Brownian motion in R^2 and |Wr(t)| be the volume of the Wiener sausage generated by β(s) until time t. In this paper, using the triangle decomposition of Wiener sausage and some exponential moment results, we obtain a moderate deviation estimate for | Wr (t) | - E|Wr (t)|.
