| dc.description | The notion of an Abstract Young (briefly: AY) representation is a natural generalization of the classical Young orthogonal form. The AY representations of the symmetric group are characterized by Adin, Brenti and Roichman in [U2]. In this paper we present several types of minimal AY representation of $D_n$ associated with standard D-Young tableaux which are a natural generalization of usual standard Young tableaux. We give an explicit combinatorial view (the representation space is spanned by certain standard tableaux while the action is a generalized Young orthogonal form) of representations which are induced into $D_n$ from minimal AY representations of one of the natural embeddings of $S_n$ into $D_n$. Then we show that these induced representations are isomorphic to the direct sum of two or three minimal AY representations of $D_n$ also associated with standard D-Young tableaux. It is done by constructing a continuous path between representation matrices where one end of the path is the mentioned direct sum; another end is the classical form of induced representation. In the last section we briefly explain how the similar results may be obtained for the group $B_n$ instead of $D_n$. | |
