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 Uniqueness Theorem and Cuntz-Krieger Uniqueness Theorem for these Leavitt path algebras, giving proofs that both generalize and simplify the classical results for Leavitt path algebras over fields. We also analyze the ideal structure of $L_R(E)$, and we prove that if $K$ is a field, then $L_K(E) \cong K \otimes_\Z… Expand
In this article, basic ideals in a Leavitt path algebra over a com- mutative unital ring are studied. It is shown that for a nite acyclic graph E and a commutative unital ring R, the Leavitt pathExpand
On the homological dimensions of Leavitt path algebras with coefficients in commutative rings
In this paper, we give sharp bounds for the homological dimensions of the Leavitt path algebra $L_K(E)$ of a finite graph $E$ with coefficients in a commutative ring $K$, as well as establish aExpand
Ideal Structure of Leavitt Path Algebras with Coefficients in a Unital Commutative Ring
For a (countable) graph E and a unital commutative ring R, we analyze the ideal structure of the Leavitt path algebra L R (E) introduced by Mark Tomforde. We first modify the definition of basicExpand

The commutative core of a Leavitt path algebra
For any unital commutative ring $R$ and for any graph $E$, we identify the commutative core of the Leavitt path algebra of $E$ with coefficients in $R$, which is a maximal commutative subalgebra ofExpand

Decomposable Leavitt path algebras for arbitrary graphs
For any field $K$ and for a completely arbitrary graph $E$, we characterize the Leavitt path algebras $L_K(E)$ that are indecomposable (as a direct sum of two-sided ideals) in terms of the underlyingExpand
Leavitt path algebras with bases consisting solely of units
Abstract An algebra is said to be an invertible algebra if it has a basis consisting solely of units. Given a field K and a finite graph E, we give a condition on E that is equivalent to that of theExpand
Morita Equivalence of Graph and Ultragraph Leavitt Path Algebras
The primary purpose of this thesis is to show every ultragraph Leavitt path algebra is Morita equivalent, as a ring, to a graph Leavitt path algebra. Takeshi Katsura, Paul Muhly, Aidan Sims, and MarkExpand
Derivations of Leavitt path algebras

The Leavitt path algebra of a graph
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 algebraicExpand
Uniqueness theorems and ideal structure for Leavitt path algebras
Abstract We prove Leavitt path algebra versions of the two uniqueness theorems of graph C ∗ -algebras. We use these uniqueness theorems to analyze the ideal structure of Leavitt path algebras andExpand
Nonstable K-theory for Graph Algebras

The $C^*$-Algebras of Arbitrary Graphs
To an arbitrary directed graph we associate a row-finite directed graph whose C*-algebra contains the C*-algebra of the original graph as a full corner. This allows us to generalize results forExpand
