Abstract

A directed graph $G$ is nonderogatory if its adjacency matrix $A$ is nonderogatory, i.e., the characteristic polynomial of $A$ is equal to the minimal polynomial of $A$. We analyze the problem whether the coalescence of difans and diwheels is nonderogatory. Also, a formula for the characteristic polynomial of the coalescence of two directed graphs is presented.
