Résume | The walled Brauer algebra appears naturally in Lie theory as centralizer algebra for mixed tensor product of the natural representation of GL(n) and its dual.
We define a degenerate affine and cyclotomic versions of the walled Brauer algebra, and we prove a higher version of mixed Schur-Weyl duality.
We show then how the usual walled Brauer algebra can be realized in an unexpected way as idempotent truncation of level two cyclotomic quotients. |
