摘要

The graph aK_m,m∇C_n is named the generalized double-wheel graph. A graph G is said to be M-integral (resp. A-integral, D-integral, D^L-integral or D^Q-integral) if all eigenvalues of its matrix M (resp. adjacency matrix A(G), distance matrix D(G), distance Laplacian matrix D^L(G) or distance signless Laplacian matrix D^Q(G)) are integers. In this paper, we completely determine all D-integral, D^L-integral and D^Q-integral generalized double-wheel graphs respectively.
