Nettet1. apr. 2024 · We achieve an extremely useful description (up to isomorphism) of the Leavitt path algebra L K (E) of a finite graph E with coefficients in a field K as a direct sum of matrix rings over K, direct sum with a corner of the Leavitt path algebra L K (F) of a graph F for which every regular vertex is the base of a loop. Moreover, in this case one … NettetIt turns out that, in many examples, the significant algebra to consider is an upper or a lower Leavitt path algebra of a bipartite separated graph, see [Reference Ara and Exel 4, Section 9]. The purpose of this paper is to show that Leavitt path algebras of weighted graphs and Leavitt path algebras of separated graphs are intimately related. Nettet1. mar. 2024 · The equivalence (1.4) is significant because many interesting questions about Leavitt path algebras are concerned with Morita equivalences between these algebras, meaning that they are concerned with the categories Mod (L F (G opp)), rather than with the algebras per se.

NettetAs an application, we show that a unital Leavitt path algebra . L K (E) with essential socle is socle-injective if and only if . L K (E) is semisimple, hence von Neumann regular. Moreover, we observed that socle-injective Leavitt path algebras are left-right symmetric. We also have provided examples to illustrate our results.
