Tóm tắt: We represent some recent results extracted in the same title manuscript by Swee Hong Chan. This includes of new points of view for the considerations the equivalent relations on recurrent configurations, distinct definitions for their levels on directed graphs (with sink and without sink). From that some nice results for the relations between the generating polynomials for recurrent configurations on a strongly connected directed graphs without sink and on its induced with a sink graph. Consequently, the independence of the choosing the sink of its generating polynomial is presented. Last, we propose some questions and planning works on this subject.
