Then M ⊗s is a(S(n, rs), FS s)-bimodule, where the symmetric group S sson s letters acts on the right by place permutations. We show that the Schur functor f rs sends M ⊗s to the (FS rs, FS s)-bimodule FS rs⊗ F(SrSs). As a corollary, we obtain the image under the Schur functor of the Lie power L s(M), exterior power s(M)of M and symmetric power S s(M). © 2011 Springer Basel AG. | Source Title: | Archiv der Mathematik | URI: | http://scholarbank.nus.edu.sg/handle/10635/104346 | ISSN: | 0003889X | DOI: | 10.1007/s00013-011-0342-2 |
