Clifford滑翔机表示理论

Clifford theory for glider representations

Frederik Caenepeel, Fred Van Oystaeyen

摘要:

经典Clifford理论研究了单$G$ -模对于某些正规子群$H \triangleleft G$到单$H$ -模的分解.在本文中,我们处理链的正规子群$1 \triangleleft G_1 \triangleleft \cdots \triangleleft G_d =G$,允许考虑片段,特别是滑翔机表示。这些由域$K$上的向量空间的下降链给出,并涉及链中出现的群的不同表示。通过选取某个正规子群$H \triangleleft G$,得到一个正规子链,从而构造出一个诱导片段结构.此外,引入了不可约的片段的概念,完成了执行Clifford理论的成分列表。

英文摘要:

Classical Clifford theory studies the decomposition of simple $G$-modules into simple $H$-modules for some normal subgroup $H \triangleleft G$. In this paper we deal with chains of normal subgroups $1 \triangleleft G_1 \triangleleft \cdots \triangleleft G_d =G$, which allow to consider fragments and in particular glider representations. These are given by a descending chain of vector spaces over some field $K$ and relate different representations of the groups appearing in the chain. Picking some normal subgroup $H \triangleleft G$ one obtains a normal subchain and one can construct an induced fragment structure. Moreover, a notion of irreducibility of fragments is introduced, which completes the list of ingredients to perform a Clifford theory.
