The eigenvalues of a graph are the eigenvalues of its adjacency matrix. This paper presents an algebraically defined invariant system of a graph. We get some bounds of the eigenvalues of graphs and propose a few open problems.
We give new bounds on eigenvalue of graphs which imply some known bounds. In particular, if T(G) is the maximum sum of degrees of vertices a~t to a vertex in a graph G, the largest eigenvalue p(G) of G satisfies p(G) <~ ~IT(G) with equality if and only if either G is regular or G is bipartite and su
