報告摘要:
In this talk, we first introduce Non-IBN (Invariant Basis Number) property of rings, and construct of Leavitt K-algebras of type (m, n) by Leavitt path algebras of separated graphs. Then we present a necessary and sufficient condition for Leavitt path algebras of separated graphs to be finite dimensional, and give a structural characterization of finite-dimensional Leavitt path algebras of separated graphs. Finally, we discuss the relations among separated graphs, Leavitt semigroups and Leavitt path algebras. This is a joint work with Qingqing Pan and Zeyuan Hou.
