Abstract

The stable rank of Leavitt path algebras of row-finite graphs was computed by Ara and Pardo. In this paper we extend this for an arbitrary directed graph. In some parts, we proceed our computation as the row-finite case while in some parts we use the knowledge about row-finite setting by applying the desingularizing method duo to Drinen and Tomforde. In particular, we characterize purely infinite simple quotients of a Leavitt path algebra. 10.1017/S0004972712000913
