NettetIn the mathematical field of graph theory, an integral graph is a graph whose adjacency matrix 's spectrum consists entirely of integers. In other words, a graph is an integral graph if all of the roots of the characteristic polynomial of its adjacency matrix are integers. [1] The notion was introduced in 1974 by Frank Harary and Allen Schwenk. [2] NettetWatanabe & Schwenk (1979) showed that these graphs are the only integral trees with a single vertex of degree more than two. They also studied the situation with two adjacent vertices of degree more than two, and proved that in that situation one has either K 1,m ~K 1,r or K 1,m ~SK 1,r .

Nettet30. mar. 2024 · Abstract. A graph is said to be distance-integral if every eigenvalue of its distance matrix is an integer. In this paper, we study the distance spectrum of abelian Cayley graphs and a class of non-abelian Cayley graphs, namely Cayley graphs over the dicyclic group T_ {4n}=\langle a,b\, \,a^ {2n}=1, a^n=b^2, b^ {-1}ab=a^ {-1}\rangle of … Nettet7 years ago.
