对称群S,在{1,…, I}通过排列坐标线性作用于@ '。由于M在这个作用下是稳定的,所以在H*(M,)上有S的表示。本文的目的是利用A (I)的表述式(1.1)给出@ S,-模H*(M,)作为归纳模和的一个公式。410
The symmetric group S, on {l,..., I} acts linearly on@’by permuting coordinates. Since M, is stable under this action there is a representation of S, on H*(M,). Our aim in this paper is to use the presentation (1.1) of A (I) to give a formula for the@ S,-module H*(M,) as a sum of induced modules. 410
