论文摘要
我们计算了$ \ mathrm {gl} _n(\ mathbb {f} _q)$的真实表示$π$的总hitney类,其中$ q $在$ 2 $对数元素上的字符值$π$的奇数是奇怪的。我们还计算了$ \ mathrm {gl} _n(\ Mathbb {r})$和$ \ mathrm {gl} _n(\ Mathbb {c})$的$ \ mathrm {gl} _n(\ mathbb {r})的真实表示的总惠特尼类$。
We compute the total Stiefel Whitney class for a real representation $π$ of $\mathrm{GL}_n(\mathbb{F}_q)$, where $q$ is odd in terms of character values of $π$ on order $2$ diagonal elements. We also compute the total Stiefel Whitney class of real representations of $\mathrm{GL}_n(\mathbb{R})$ and $\mathrm{GL}_n(\mathbb{C})$.
