Witt代数的单模扩张

Extensions of simple modules for the Witt algebra

Khalid Rian

摘要:

Witt代数$W$的不可约表示是完全已知的。不可约$U_χ(W)$ --模的分类首先由Chang建立,后来由Strade简化。本文的目的是给出简单$U_χ(W)$的扩展的分类--具有高度为$-1,0,1$和$p-1$的$p$ --特征$χ$的模,其中$p$表示基域的特征。

英文摘要:

The irreducible representations of the Witt algebra $W$ are completely known. A classification of the irreducible $U_χ(W)$--modules was first established by Chang and later simplified by Strade. The aim of this article is to give a classification of the extensions of the simple $U_χ(W)$--modules having $p$--character $χ$ of height $-1,0,1$ and $p-1$ where $p$ denotes the characteristic of the ground field.
