外尔群的Specht模的子模

Submodules of Specht Modules for Weyl Groups

Sait Halicioğlu

摘要:

G.D.James给出了任意域上对称群的所有不可约模的构造,这些不可约模在特征为零的域的情况下可约为Specht模。Halıcıolu和Morris描述了James对一般外尔群的工作的可能扩展,其中Young tableaux用根系来解释。本文给出了外尔群的Specht模的子模的构造.

英文摘要:

The construction of all irreducible modules of the symmetric groups over an arbitrary field which reduce to Specht modules in the case of fields of characteristic zero is given by G.D.James. Halıcıoğlu and Morris describe a possible extension of James' work for Weyl groups in general, where Young tableaux are interpreted in terms of root systems. In this paper we show how to construct submodules of Specht modules for Weyl groups.
