appeared along with Jannsen's ,theorem, that the category of motives is abelian semi-simple if and only if the equivalence relation is numerical equivalence. The proof of this ,theorem, is beautiful, simple and short. (The main tool is the ,double,-,centralizer theorem,.) I will try to do it justice in my lectures.

The ,centralizer, of the identity is the whole group, which is of index $1$. $1=1$. $\endgroup$ – Hagen von Eitzen Sep 15 '15 at 15:43 $\begingroup$ thanks. now I am happy. thanks for correctness. $\endgroup$ – henry Sep 15 '15 at 15:44

Towards a Schur-Weyl Duality for the Alternating Group

This is a ,key, first step in coming up with a version of Schur-Weyl du-ality for this group. The ,centralizer, of the action of A n on k-fold tensor copies of its permutation representation should be a super-algebra of the partition algebra.
