关于Leavitt路代数上单模的注记

Notes on Simple Modules over Leavitt Path Algebras

Kulumani M. Rangaswamy

摘要:

给定任意图E和任意域K,利用发出无穷多条边的顶点构造了K上图E的Leavitt路代数L上的一类新的简单左模.相应的零化本原理想的描述,并用于表明,这些新的类简单的L-模是不同的(即非同构)的任何以前已知的简单的模块。利用E中由路诱导的幂等元的布尔子环,给出了简单L-模的不同同构类集合的基数的界。我们还补充了关于有限图E的Leavitt路代数L(E)的其它信息,其中每个简单左模都是在有限图E上表示的。

英文摘要:

Given an arbitrary graph E and any field K, a new class of simple left modules over the Leavitt path algebra L of the graph E over K is constructed by using vertices that emit infinitely many edges. The corresponding annihilating primitive ideals are described and is used to show that these new class of simple L-modules are different from(that is non-isomorphic to) any of the previously known simple modules. Using a Boolean subring of idempotents induced by paths in E, bounds for the cardinality of the set of distinct isomorphism classes of simple L-modules are given. We also append other information about the Leavitt path algebra L(E) of a finite graph E over which every simple left module is finitely presented.
