| Apr 25, 2020 at 17:41 | comment | added | Monty | Thank you very much! The reference you informed me is the very one I am searching for. There is another action like taking contragredient representation. But I am still wondering why for $GL(n)$, there is no such involution action but only permutation. Do you know some intuitive reason for why there does not Weyl group element corresponding to taking $g^{-1}$ to each components of $GL(n_i)$? | |
