任意图的Leavitt路代数的Socle理论

Socle theory for Leavitt path algebras of arbitrary graphs

Gonzalo Aranda Pino, Dolores Martin Barquero, Candido Martin Gonzalez, Mercedes Siles Molina

摘要:

本文的主要目的是给出任意图的Leavitt路代数的柱脚理论。我们使用的desingularization过程和组合的方法来研究森田不变的性质有关的柱脚和表征,分别。把具有非零基柱的Leavitt路代数描述为具有线点的Leavitt路代数,并证明了线点生成Leavitt路代数的基柱,从而推广了文[12]中关于行有限图的结果(但方法不同).得到了Leavitt路代数的基柱的一个具体描述:它是基域上矩阵环(有限或无限大小)的直和。给出了分次唯一性定理和Cuntz-Krieger唯一性定理的新证明,大大缩短了原证明.

英文摘要:

The main aim of the paper is to give a socle theory for Leavitt path algebras of arbitrary graphs. We use both the desingularization process and combinatorial methods to study Morita invariant properties concerning the socle and to characterize it, respectively. Leavitt path algebras with nonzero socle are described as those which have line points, and it is shown that the line points generate the socle of a Leavitt path algebra, extending so the results for row-finite graphs in the previous paper [12] (but with different methods). A concrete description of the socle of a Leavitt path algebra is obtained: it is a direct sum of matrix rings (of finite or infinite size) over the base field. New proofs of the Graded Uniqueness and of the Cuntz-Krieger Uniqueness Theorems are given, shorthening significantly the original ones.
