Integral graphs
NettetLet be a graph. If all the eigenvalues of the adjacency matrix of the graph are integers, then we say that is an integral graph. A graph is determined by its spectrum if every graph cospectral to it is in fact isomorphic to it. In this paper, we investigate some algebraic properties of the Cayley graph , where ( is a prime integer and ) and .

NettetTriple Integral Visualizer. Author: tdr. Topic: Definite Integral, Integral Calculus. Shows the region of integration for a triple integral (of an arbitrary function ) in rectangular coordinates. Note: To display a region that covers a large area over the -plane, it may help to turn density down first (and zoom out if necessary). 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 …
