Green’s relations on the endomorphism monoid of a graph. (English) Zbl 0853.05046
Summary: Green’s relations on the endomorphism monoid of a graph are explicitly described. In particular, it is revealed that for endomorphism monoids of some special classes of graphs, Green’s relations may possess some distinct combinatorial features.
