正则单形的平均宽度

Mean Width of a Regular Simplex

Steven R. Finch

摘要:

平均宽度是n维凸体上的测度。1997年,在电气工程文献中出现了一个正则n-单形平均宽度的积分公式。因此,当n<=6时,n+1个正态分布变量的样本的期望范围的表达式,延续到正则n-单形的宽度。作为另一个结果,当n->infty时,平均宽度的精确渐近性变得可用。

英文摘要:

The mean width is a measure on n-dimensional convex bodies. An integral formula for the mean width of a regular n-simplex appeared in the electrical engineering literature in 1997. As a consequence, expressions for the expected range of a sample of n+1 normally distributed variables, for n<=6, carry over to widths of regular n-simplices. As another consequence, precise asymptotics for the mean width become available as n->infty.
