分数布朗单的幂函数随机积分逼近
APPROXIMATION TO THE FRACTIONAL BROWNIAN SHEET FROM STOCHASTIC INTEGRALS OF POWER FUNCTION

本文研究了分数布朗单的逼近问题.利用Wiener积分，得到了分数布朗单的幂函数型随机积分逼近.
In this paper, we study an approximation of the fractional Brownian sheet. By using the Wiener integrals, we obtain the approximation by stochastic integrals of power function
