Abstract For any row-finite graph E and any field K we construct the Leavitt path algebra L ( E ) having coefficients in K . When K is the field of complex numbers, then L ( E ) is the algebraic analog of the Cuntz–Krieger algebra C ∗ ( E ) described in [I. Raeburn, Graph algebras, in: CBMS Reg. Conf. Ser. Math., vol. 103, Amer. Math. Soc., 2005]. The matrix rings M n ( K ) and the Leavitt algebras L ( 1 , n ) appear as algebras of the form L ( E ) for various graphs E . In our main result, we… Expand
Centers of Path Algebras, Cohn and Leavitt Path Algebras
This paper is devoted to the study of the center of several types of path algebras associated to a graph E over a field K. First we consider the path algebra KE and prove that if the number ofExpand
On simple modules over Leavitt path algebras
Abstract Given an arbitrary graph E and any field K, a new class of simple modules over the Leavitt path algebra L K ( E ) is constructed by using vertices that emit infinitely many edges in E. TheExpand
Leavitt path algebras with coefficients in a commutative ring
Given a directed graph E we describe a method for constructing a Leavitt path algebra $L_R(E)$ whose coefficients are in a commutative unital ring R. We prove versions of the Graded UniquenessExpand
Classification of Leavitt Path Algebras with Two Vertices
We classify row-finite Leavitt path algebras associated to graphs with no more than two vertices. For the discussion we use the following invariants: decomposability, the $K_0$ group, $\det(N'_E)$Expand
Leavitt path algebras satisfying a polynomial identity
Leavitt path algebras L of an arbitrary graph E over a field K satisfying a polynomial identity are completely characterized both in graph-theoretic and algebraic terms. When E is a finite graph, LExpand
Socle theory for Leavitt path algebras of arbitrary graphs
The main aim of the paper is to give a socle theory for Leavitt path algebras of arbitrary graphs. We use both the desingularization process and combinatorial methods to study Morita invariantExpand
Corners of Leavitt path algebras of finite graphs are Leavitt path algebras
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 $K$,Expand
Leavitt path algebras of separated graphs

Commutator Leavitt Path Algebras
For any field K and directed graph E, we completely describe the elements of the Leavitt path algebra LK(E) which lie in the commutator subspace [LK(E), LK(E)]. We then use this result to classifyExpand
Notes on Simple Modules over Leavitt Path Algebras
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.Expand
