Leavitt路代数分类中的流不变量

Flow invariants in the classification of Leavitt path algebras

G. Abrams, A. Louly, E. Pardo, C. Smith

摘要:

我们分析的背景下,莱维特路径代数的一些图形操作的背景下引入的符号动力学威廉姆斯,帕里和沙利文,弗兰克斯。我们表明,这些操作诱导相应的莱维特路代数的森田等价。作为结果,我们得到了我们的两个主要结果:第一个给出了充分条件的Leavitt路代数在某一类是Morita等价的,而第二个给出了充分条件产生同构。我们讨论一种可能的方法来确定这些条件是否也是必要的。在最后一节中,我们提出了许多额外的操作图保持森田等价(分别,同构)的相应的莱维特路代数。

英文摘要:

We analyze in the context of Leavitt path algebras some graph operations introduced in the context of symbolic dynamics by Williams, Parry and Sullivan, and Franks. We show that these operations induce Morita equivalence of the corresponding Leavitt path algebras. As a consequence we obtain our two main results: the first gives sufficient conditions for which the Leavitt path algebras in a certain class are Morita equivalent, while the second gives sufficient conditions which yield isomorphisms. We discuss a possible approach to establishing whether or not these conditions are also in fact necessary. In the final section we present many additional operations on graphs which preserve Morita equivalence (resp., isomorphism) of the corresponding Leavitt path algebras.
