Tóm tắt: Starting from a directed graph, we associated a very simple mathematical object, the so-called the talented monoid to the graph. We show how this monoid can capture many geometrical properties of the directed graph, such as if a graph has a cycle with an exit, or how many cycles without exists are there in the graph, the period of the graph, etc…. If time permits we will look at the talented monoids for higher rank graphs. The graded classification conjecture for Leavitt Path Algebras can also be formulated using talented monoid, which is then can be extended to the conjecture on graph C*-algebras.
