Abstract

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 path algebra LR(E) is a direct

sum of minimal basic ideals and that for a commutative ring R and a graph

E satisfying Condition (L), the Leavitt path algebra LR(E) has no non-zero

nilpotent basic ideals. Uniqueness theorems for Leavitt path algebras over

commutative unital rings are also discussed.

Keywords

Leavitt path algebra, basic ideal, minimal basic ideal, uniqueness theorem
