tailieunhanh - Graded version of Exel’s Effros-Hahn conjecture for leavitt path algebras

In this paper, we prove a graded version of Exel’s Effros-Hahn conjecture for Leavitt path algebras. More concretely, we show that any graded primitive ideal of the Leavitt path algebra is the annihilator of a module induced from a graded simple module over an isotropy group algebra. |
