The injective envelope of simple modules over Leavitt path algebras II: simples arising from exclusive cycles

G. Abrams, F. Mantese, A. Tonolo

Let $K$ be any field, $E$ any directed graph, and $L_{K} (E)$ the associated Leavitt path algebra. As described first by Chen, and subsequently generalized by Ara and Rangaswamy, for…

The injective envelope of simple modules over Leavitt path algebras I: simple left ideals

G. Abrams, F. Mantese, A. Tonolo

Let $K$ be any field and $E$ any directed graph. We characterize up to isomorphism the simple (i.e., minimal) left ideals of the Leavitt path algebra $L_{K} (E)$ . Then, for each simpl…
