扩展模和Ore扩张

Extended modules and Ore extensions

Vyacheslav Artamonov, William Fajardo, Oswaldo Lezama

摘要:

在本文中,我们研究了扩展模块的一个特殊的Ore扩展。我们假设$R$是一个环,$A$表示Ore扩张$A:=R[x_1,\dots,x_n;σ]$,对于每个$1\leq i,j\leq n$,$σ$是$R$、$x_ix_j=x_jx_i$和$x_ir=σ(r)x_i$的自同构。在环$R$上引入一些额外的条件,证明了这类非交换环的Vaserstein定理,Quillen定理,Horrocks定理和Quillen-Suslin定理.

英文摘要:

In this paper we investigate extended modules for a special class of Ore extensions. We will assume that $R$ is a ring and $A$ will denote the Ore extension $A:=R[x_1,\dots,x_n;σ]$ for which $σ$ is an automorphism of $R$, $x_ix_j=x_jx_i$ and $x_ir=σ(r)x_i$, for every $1\leq i,j\leq n$. With some extra conditions over the ring $R$, we will prove Vaserstein's, Quillen's patching, Horrocks' and Quillen-Suslin's theorems for this type of non-commutative rings.
