Leavitt路代数的柱脚列

The socle series of a Leavitt path algebra

Gene Abrams, Kulumani M. Rangaswamy, Mercedes Siles Molina

摘要:

研究了任意图$E$和域$K$的Leavitt路代数$L_K(E)$的升Loewy柱脚级数.我们对Loewy柱脚系列的某些元素$S_λ$有$L_K(E)=S_λ$的图$E$进行了分类.然后,我们表明,任何序数$λ$存在图$E$,使Loewy长度的$L_K(E)$是$λ$。此外,如果$E$是行有限图,则$λ\leq ω$(第一无限序数)。

英文摘要:

We investigate the ascending Loewy socle series of Leavitt path algebras $L_K(E)$ for an arbitrary graph $E$ and field $K$. We classify those graphs $E$ for which $L_K(E)=S_λ$ for some element $S_λ$ of the Loewy socle series. We then show that for any ordinal $λ$ there exists a graph $E$ so that the Loewy length of $L_K(E)$ is $λ$. Moreover, $λ\leq ω$ (the first infinite ordinal) if $E$ is a row-finite graph.
