On the spectrum of an extremal graph with four eigenvalues
In this note we study some properties of the spectrum of a connected graph G with four different eigenvalues, and (spectrally maximum) diameter three. When G is regular, this is the case, for instance, when G is a distance-regular graph. © 2006 Elsevier B.V. All rights reserved.
متن کاملExtremal Properties of Eigenvalues for a Metric Graph
Let Γ be a connected finite graph; by V we denote the set of its vertices, and by E we denote the set of its edges. If each edge e is considered as a segment of certain length l(e) > 0 then such a graph is called a metric graph. One can find a good survey and numerous references in [K]. A metric graph with a given combinatorial structure Γ is determined by a vector of edge lengths (l(e)) ∈ R + ...
