Abstract

The Garnir relations play a very important role in giving combinatorial constructions of representations of the symmetric groups. For the Weyl groups of type C-n, having obtained the alternacy relation, we give an explicit combinatorial description of the Garnir relation associated with a Delta-tableau in terms of root systems. We then use these relations to find a K-basis for the Specht modules of the Weyl groups of type C-n.
