RT preprint T1 Towards a K-theoretic characterization of graded isomorphisms between Leavitt path algebras A1 Ara, P. A1 Pardo Espino, Enrique A2 Matemáticas AB Hazrat gave a K-theoretic invariant for Leavitt path algebras as graded algebras. Hazrat conjectured that this invariant classifies Leavitt path algebras up to graded isomorphism, and proved the conjecture in some cases. In this paper, we prove that a weak version of the conjecture holds for all finite essential graphs.
