Leavitt Path Algebras with Coefficients in a Commutative Unital Ring

Abstract

In addition to extending some facts from field coefficients to commutative ring coefficients for Leavitt path algebras with new shorter proofs, we also prove some results that are new even for field coefficients. In particular, we show that the ideal lattice of a Leavitt path algebra embeds into the ideal lattice of the path algebra of the same digraph, we construct a new basis for a Leavitt path algebra of polynomial growth and give a formula for the Gelfand-Kirillov dimension of a Leavitt path algebra in terms of its digraph.
