Abstract: There are six different classes of endomorphisms for a graph. The sets of these endomorphisms always form a chain under the inclusion of sets. For a more systematic treatment of different endomorphisms, Böttcher and Knauer proposed the concepts of the endomorphism type and the endomorphism spectrum of a graph in 1992. In this paper, we studied endomorphism types and endomorphism spectra of double fan graphs.
